I like V1 but often dont have the time to watch programs on telly, too busy with other things!
Ive recently become addicted to lost on demand, so if sky one keep up the lost stuff, when i get to series 4 i may need to purchase some sky action!
However V1 is really good, all the shows ive watched on there and all the upcoming shows look amazing, along with this lost series 1 2 3 are on demand HD which is pretty awsome
So overall id say V1, as it has more good shows on it than sky1
