I've always sorta felt like Cream never reached their full potential
I like them and everything but have sometimes disparagingly referred to them as "Clean", because they're often a bit too slicker my ears. They never got gritty and really cut loose, especially compared to The Experience (not really a fair comparison I know, but the 2 groups are still obviously often compared to one another for a reason). Yes, they stretched out when they played live but it still often sounded a bit safe (and Bruce's bass was always hilariously yet distractingly loud). I've also never been a big fan of Baker as a drummer, songwriter or human being (though I did enjoy the documentary about him). Bruce wrote better songs and was actually a good singer and seems like a pretty dominant force but a lot of my favorite Cream moments like "Brave Ulysses" (their best song IMO) and the riff from "Sunshine" (which he infamously didn't get credit for originally).
From a guitar playing perspective, his best moment w/ Cream was the version of "Crossroads" from the 3rd album (which seems to be a pretty common opinion) but all in all, my favorite playing of his is on the Bluesbreakers album (and other non-LP cuts like "I'm Your Witchdoctor"). I've never been a "Clapton Is God" believer but he's a ####in beast on those recordings. He also got a few good licks in w/ The Yardbirds but was pretty constrained and that group got better and more interesting after he left.
