Personally, i think pulse is better then pure.
Reasons? Pulse is more refined, and not as graphically cluttered imo, and like previous posts, the AI isnt nearly as good as pulses. The skin editor was a great addition to the already awesome game, but in respect, i also think that pure's tracks were much better in terms of uniqueness and artistic areas. Pulse, to me, is one of the few wipeouts that i can play for days on end, pure just isnt one of them.
