III has a better and more interesting story telling. But gameplay wise I really like the starcraft 1 system without the heros. I think warcraft 3 adds too much complexity and gimmickry that takes away from fun RTS gameplay.
That said, Warcraft 3 mods were the shit. There were so many fun and inventive modes of play that you could just barely do with starcraft and not at all with warcraft.
Warcraft 3 custom map mod was the birth of Defense of the Ancients Allstars which then became its own game by Valve as Dota 2 (and Blizzard was pissed and tried legal stuff to reclaim) which now became Deadlock = Dota 3.
