What are the pros and cons of Bitdefender GravityZone Ultra vs Symantec End-User Endpoint Security?

Hello,

I work as an IT engineer at a Healthcare company (size: 1000+ employees).

Currently, I'm researching these 2 endpoint security solutions: Bitdefender GravityZone Ultra and Symantec End-User Endpoint Security. 

Can you help me in understanding the main differences and the pros and cons of these solutions?

I appreciate the help.
