More likely than not yes, user error or factory installation error.
You say PressFit BB's are stupid, yet most of the worlds industries press bearings in rather then screw them into threads (or push them into cups to be then screwed into threads?!?!). They've been doing it for a long time, and it's been working pretty well so far.

I do nearly all my maintenance myself and that's where threaded BBs have an advantage (in terms of availability of tools and ease of installation) - also the idea of bashing a part of your bike with a hammer seems incredibly crude. And, if you saw all the seatpost chat, you might say that I have an unreasonable obsession with replaceability. So they're not for me.
But that wasn't the point; I was just curious about the creaking aspect though

Not into carbon fibre bearing housings though. That's one thing that people who use composites a lot like F1 teams and aeronautical engineers try very, very hard to avoid. If you look at an F1 gearbox with a composite housing, all of the bearing carriers will either be bolted on or will be alloy shells co-moulded into the housing. You can't get sufficiently tight tolerances with carbon alone.

So do PF BBs not creak? Is it user error? (I think they're stupid regardless of creaking)
