if you aren't used to regular pcvr you aren't going to notice it, but if you have you'll have no trouble getting used to it at all and won't consider much of a drawback
the latency will be pretty much the same between wired and wireless if your router isn't struggling to send data back and forth 
through a decent but fairly old 5ghz router (linksys wrt32x) I was getting about 10~16 (usually 13 total) additional ms of latency compared to a direct pcvr connection
