IRL chatting gets you immediate feedback from the guy you're talking to in the form of body language and facial microexpressions. In VR, the only expressions you get are the ones mapped to someone's avatar and if they don't have FBT you don't really get any body language at all. I also find it a lot easier to just get completely ignored in VR than it is IRL, which you can chalk up headset FoV and resolution being crap. 
I enjoy VRchat but it's been hard as fuck actually walking up and talking to people. It's easy to feel like you're not welcome and the guy you're talking to wants you to fuck off.
