I've played both just recently and I still think I enjoy SM64 more... I just find the controls and jumping to be superior, and i find the challenges to be more fun as well.
Still, Banjo & Kazooie certainly looks better and has its own charm, so I'm not really comfortable declaring one superior to the other. What is clear, of course, is that Banjo and Kazooie basically just took the SM64 template, replaced mario with a bear and a bird, and slapped some better graphics on it with an expanded hub world. For that reason I can see why some might prefer it to SM64.
Really, it SHOULD be better than its predecessor, and I think a person who plays both for the first time today would likely enjoy Banjo more, but it's also clear that there'd be no recognizable banjo and Kazooie game without SM64 when once considers just how many ideas Rare clearly borrowed from them.
Still, Banjo Tooie was better than the first... That's probably a better argument to be having.
