Gibson has made a ton of good pickups, but who hasn't? I'm seeing and hearing examples of great pickups even on mid-range import Gretsches and Schecters these days, very recently I heard newer Epiphone pickups with the covers removed that sounded great.
I don't know where you are on your journey, but I would tell my younger self to just grab a ziplock bag's worth of used bridge pickups as cheap as you can find them, based on the players you like who are using them, try them all and take notes, email a few non-expensive manufacturers for recommendations based on your notes. pick those up and try them too. Pick a favorite and try to find a match with the neck (or start with the neck if your main pickup). Then adjust your amp and other gear and carry on.
I won't say pickup hunting is a waste of time, perfecting your thing always important, but for most of us it's kind of like trying to find the best brand of shampoo. There's definitely diminishing returns and better things to do after a certain point. I bet I could have taken a graduate course with the time I've invested in the things and paid for a couple more.
Gibson pickups... overall, I think compare fine with humbuckers you'd get from the more common manufacturers. Mnay times they sound great stock with he models they appear in but I wouldn't pay a premium to acquire them though. I would narrow down what you're hunting for sound-wise even if not trying to emulate anybody. Give a half dozen youtube examples of what you think a good guitar sound is or at least what you're hoping to get near with this guitar project, would probably help you most.
Plus you'll have to figure out where you are on things like versatility, some people want a guitar that can cover a range where others tends to keep it simple on each individual guitar. In the earlier case you might be looking at humbuckers not just for their normal use case, but also for what they sound like coil tapped or split. That's not really my way but a lot of Warmoth folks have setups like that who could probably help you avoid some that wouldn't work.
