Not really, vent is considered better because it lags less. Although i have never used vent, i've heard there is barely any lagg compared to ts, where there is around 1-2 seconds...
But, with a browser game... What does one or two seconds matter? xD Also, people say ts has better sound quality? Dunno if its strue, but i'm in ts whenever i game, so feel free to come in and have a lil chat =)

EDIT: oh, acording to pommeh vent is cleaner.... Meh, i'm pretty sure the lagg thing is true though.... >.<
