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

"The group chat is very good."
"The tool's integration with OneNote and Power BI is good. The current version of Microsoft Teams is significantly more user-friendly compared to previous versions. I find it easy to handle any user needs and provide assistance. The device installation process is straightforward, and configuring it for users is not complicated. This seamless and user-friendly experience makes it easy to connect with everyone."
"The most valuable features of Microsoft Teams are video conferencing, chat function, and the one that shows you that you've got new messages."
"The installation is very, very easy."
"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."
"I think what the team likes most is the improvements when it comes to communication."
"We can build a team with a group of people and upload documents."
"Integration with document management capabilities and video conferencing."
"The most valuable feature is that we can easily integrate different workloads and the alerts are reliable. Also because it allows us to use it as a monitoring tool sometimes."
"Slack is a really easy collaboration tool to use and many companies are adopting this popular tool."
"The most valuable features of Slack are basic chatting, file sharing, and screen sharing."
"The feature that I have found most valuable is communication between team members."
"Slack helps me to read bulk messages."
"The portal is at its best version now."
"Nowadays, we don't need to visit an HR portal. Our marketing and human resources teams directly share details about birthdays, upcoming events, and important dates in Slack. Whether it's a training event, a company-wide gathering, or a social event, all the information is shared there. This keeps us all updated."
"The product has the ability to scale."
 

Cons

"The solution's customer support should be faster and more responsive."
"The solution needs to be more stable. I have found Zoom to be more stable than Teams."
"Microsoft Teams can start being more interactive and intuitive by implementing artificial intelligence and machine learning."
"There are a lot of frequent updates, which is a shortcoming of the tool."
"The product needs to improve its stability."
"I would like to get less frequent updates from the solution."
"Whiteboard tool not embedded in the solution."
"The solution’s pricing could be improved."
"The only area of concern that I have is with the inability to preview received documents without having to download them first."
"It would be better if Slack had a 'select all' option to delete all the files."
"It would be highly advantageous if it could incorporate calendar information from sources like Outlook or Gmail, providing users not only with meeting schedules but also a comprehensive daily agenda view."
"Slack should add a feature to schedule meetings."
"We do experience issues when trying to log in on Slack."
"The mobile app needs improvement. It consistently misses notifications."
"Slack is not as strong as competitors like Teams when it comes to things like video meetings and audio meetings."
"Slack's interface is not simple for me. It's not a user-friendly interface"
 

Pricing and Cost Advice

"I would rate the solution's pricing a nine out of ten."
"Microsoft Teams is expensive compared to other solutions."
"I don't think the solution is as expensive as big Webex licenses. It doesn't usually offer one-on-one licenses, so it's hard to compare. It's more expensive than the Google equivalent, but you can't replace Microsoft Teams with Google's offering."
"I rate Microsoft Teams an eight out of ten for its pricing."
"I rate the tool's pricing a six out of ten. Its pricing is fixed."
"The price is relatively high."

"The solution's pricing is average."
"I would rate the tool's pricing a four out of ten."
"The tool's pricing could be cheaper."
"It's on the more expensive side."
"We use the free version that does not have a license."
"The solution is cheap in my country."
"Slack is definitely worth the money."
"It is less expensive than one of its competitors."
"The solution’s pricing is cheap."
