Both looked uneven to me. I thought Conker had a more cohesive look to it than Kameo, even though parts of Kameo was clearly more impressive. I wouldn't be surprised if that's the case for early PS4 and xbox3 games too; although, Killzone 4 looked like it has Resistance's problem of being consistently blah.
PDZ had great multiplayer, once you got past how badly it controlled. I didn't and still don't like Kameo. First played it on a friend's 360 and thought it was almost as bad as rare's star fox game; tried it again a month or two ago and still didn't like it. From there Rare's games got better with the Viva Pinata series and Banjo Nuts and Bolts. Nuts and Bolts is still my favorite 360 game.
