Things I still like about Vent:
Better voice quality (maybe most of you TS people just use shitty codexes, though, I dunno)
Things I like about TS:
Everything else about the client is superior
That honestly about sums it up.
TS seems more reliable in my experience, easier to set up/use (lots of win7 issues with vent) and the voice quality is "acceptable" - especially considering the reduced latency, which while not a big deal for most of us, can cause considerable lag for some.
Personally I would set up a ventrilo server if I were to set a voice server up, despite the fact that I personally prefer TeamSpeak, but it would really depend on what I was going to be using it for.
You know you want those call pictures next to your name.

Yeah but you can put words in front of people's names in VENTRILO!!!
