The problem with big brands is that they are run by accountants in battle with engineers, the bean counters nearly always win. And the same again for the sub contractors.
Cervelo is an example of an innovative brand that quality went down hill as it grew.
I usually put all youtube pundits in one box. Most grifters/trying to sell you something "link in bio" etc.
Sure, PF BBs suck in comparison to threaded but does that mean one needs to die on a hill to defend a £250 BB sold by a grifter?
Personally I trust the big bike brands that employ multiple engineers and subject experts with much higher QC standards than cottage/vlogger industry.
