Sure thing! A couple keys differences:
1) Avatars - as you mentioned
2) Walkie-talkie - most virtual offices have a call analogy, where you call someone to speak. In Pragli, you don't call - you just jump straight into a conversation, but the other side is muted (to protect their privacy). Here's my blog post on this:

3) Some solutions have a very literal office (with a floor plan, etc) - we have a more virtual analogy
4) From what we hear, we have higher quality audio, video, screen share than others (I encourage you to evaluate for yourself)
