Who's a greater player, Wilt Chamberlain or Kareem Abdul Jabar?

Wilt was dominant during his prime, scoring 100 points in a game and averaging over 50 in a season. But Kareem was durable, playing all of 20 seasons and scoring more points than any other player in NBA history. Wilt won 2 titles but Kareem won 6. Wilt won 4 regular season MVP's, Kareem won 6. So, as between dominance and durability, I'll go for the latter so I'm picking Kareem. Besides, if only for inventing the skyhook, the single most devastating offensive weapon in all of sports, Kareem should be the greatest big man ever.
