Best Quake game?

So I'm too young to have enjoyed Quake growing up, but I've heard a lot of cool stuff about it. So I'm just wondering, what's the best/most active Quake game?

Well i am young to and have not played all of them but i've recently been playing quake 3 arena and i run it on a netbook A NETBOOK  

Do you get it from Steam?

  • Single player: Quake 2
  • Multiplayer: Quake 2, Quake III or Quake Live 

Well, if you don't mind some ads and want to play now, Quake Live is a decent service. It's not uncommon to find Qain streaming it.
