Well, Virtua Tennis supposedly has all the online features of the HD versions. But GST has Wimbledon and some classic players (if you care about that).
I believe Virtua Tennis has a bit of a different control scheme than GST, in that it's not actually 1:1, they just use MotionPlus to add accuracy to your shots (works great from what I read). But in GST you have to hold down a button if you want to lob or do a drop shot, while in VT you just .... do a lob or a drop shot.
Assuming you don't care about the art styles, I would honestly wait a little bit longer for some actual reviews before you decide.
