Santhosh Varghese - PeerSpot reviewer
Whiteboard and content sharing features are good
I would rate Teams's stability as a nine out of ten. However, some recent updates have made it less stable. I find it a little bit choppy. Sometimes, I find the network quality is not very good with low bandwidth. So, sometimes, when you have low bandwidth the quality becomes very poor. So, you have to optimize your usage.
PaulButticaz - PeerSpot reviewer
A competitive solution that improves collaboration and productivity
Slack has been around for a long time, and it's an industry leader. Of course, Salesforce owns Slack now and is starting to integrate into it. I have attended Slack conferences and met with product and support managers. They're an excellent organization. Choosing Slack depends on the organization's size, so you need to plan your deployment and make sure you put some controls and standards in place and not just turn it on. If you're a Slack shop, you will have to have something like a Zoom or Microsoft Teams platform for when you need to do video conferencing internally or externally. Many shops have both products, but they use Slack for collaboration, chat, and so on, and use Teams for video and audio conferences. At the end of the day, Slack is missing those capabilities, so either you're going to be a Slack/Zoom shop or you're going to be a Microsoft Teams shop. I rate Slack an eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like the whiteboard feature as well. I'm able to scribble some stuff if I need to explain a couple of items."
"Microsoft Teams is much more stable than other solutions like Skype for Business."
"We can share all files on Microsoft Teams directly. It is integrated with Outlook."
"We like that you can get a lot of users on one call without the call actually failing or losing quality. Hosts can connect, if I recall correctly, up to 90,000 people. If you need a massive company-wide meeting, you can do it."
"It is a stable solution."
"The solution's most valuable feature is Microsoft Planner. Most users now use Microsoft Teams since many companies use Microsoft Office 365. It's built into the plan, and they use the same email address for a single sign-on."
"The feature for video conferencing capability works efficiently for remote meetings."
"I like the product's screen share feature since we can explain things to the users at the other end using it. The solution helps me to establish a virtual connection with my team."
"The portal is at its best version now."
"You can create channels between teams internally and externally, which is great. There is a lot of security with Slack internal, which is what I value."
"Overall, it is a good idea as it works better than most solutions out there."
"The solution's initial setup process is easy."
"The product gives the best user experience."
"The solution has a great user interface and functionalities. It has good features that we can use. We can integrate any third-party application with Slack so that it provides you with insights and updates in real-time on Slack itself."
"Slack helps me to read bulk messages."
"Slack is a powerpack bundle of features that help small or large organizations to handle teams and their tasks."
 

Cons

"The product should improve its security."
"The product should provide a to-do list feature."
"The future scalability can include the integration of planners, project management tools, SharePoint, and more applications that are used."
"Its stability could be better."
"Microsoft Teams is quite demanding on bandwidth, which has been a problem during the COVID situation because we don't get enterprise-class bandwidth at home."
"The solution should improve internal and external data expansion. I am not able to send records to an external member who has been added to the call. I am only able to send the file to the internal member. These features should be enabled in that Teams so that during the call, we can share the document file and discuss at the same time."
"We had some upstream outages which impacted collaboration."
"They should add an integration API for the solution."
"For me, the only thing I can say is that every time somebody sent me an attachment, the attachment was listed somewhere, and then I had to open the conversation and go to the individual to open it. So there is no handy repository or an easy way to quickly look at attachments. For me, that was a bit difficult."
"Slack's interface is not simple for me. It's not a user-friendly interface"
"Slack does not have videoconferencing capabilities, which would have been nice."
"There could be a read function so that when you send a message, instead of the other person having to add a reaction, you know that the message went through."
"The solution’s initial setup is not very easy."
"I would like the text in chat to be more customizable."
"Notifications are not as good as they could be (especially for mobile)."
"The video calling experience on Slack needs improvement."
 

Pricing and Cost Advice

"The tool's price is high and I would rate it an eight out of ten."
"I would rate the solution's pricing a nine out of ten."
"The solution has a reasonable price in the market."
"The tool's price is part of MS Office 365 and I would rate its pricing five out of ten. The tool's licensing costs are monthly."
"Its pricing is reasonable."
"The product's pro accounts are cheap."
"There is a need to pay for the licensing... I know that the payments are made on a yearly basis...There are no extra costs in addition to the standard licensing."
"The solution is priced high."
"The pricing can range up to about twenty bucks a user. You can spend a lot of money, especially if you're talking about thousands of users. Generally speaking, Slack is less expensive than Teams. Slack doesn't include all the bells and whistles that Teams does. So you can go from a $6 license in Microsoft 365 to a $50 license per user per month, and there's a lot more you can do in the $50 license."
"When it comes to pricing, it is on the expensive side."
"We use the free version that does not have a license."
"It is an expensive tool. We pay 15 to 20 USD monthly per user."
"The solution is cheap in my country."
"The solution is expensive."
"Slack is not the cheapest solution, but that's okay."
"It is less expensive than one of its competitors."
