The best thing about unifi is that it helps us to integrate our system with service now tickets easily. It also supports all the version of service now tickets. They provide good support in terms of documentation as well as training sessions. Their product is quite costly compared to others. So if your budget is not so large then use them because they are very good but if you have big budget then go for other platforms like zoho or gsuite. We used unifi for one of our clients and we integrated their system with service now tickets.
