I have the BB30 frame, Cannondale CAAD10, because my 12 year old C’dale with good ole fashioned threaded BB shell suffered a cracked dropout.To my surprise, C’dale, replaced it under warranty.I went with BB30 crankset...Sram Red..because I didn’t want to mess with adaptors and such, which seemed to cause more problems than they solved. I considered praxis with Shimano cranks at the time...praxis did seem a good design, but decided to go with the lighter option.

In the 3 years and many miles since getting the bike, I have had one bearing seize (almost immediately, I think the LBS that built the frame damaged it when they pressed it in) and very occasional (twice in 3 years) minor creak that so far has been easily cured by taking cranks out and cleaning everything, which is no different than life was with a threaded shell.I keep waiting for the dreaded incurable BB30 creak but it hasn’t happened, and I didn’t even use retaining compound when I replaced the aforementioned seized bearing (ignorance). In fact,I researched BBInfinite last year because I was having a creak that I thought was BB related, but it turned out to be a cracked saddle rail.New saddle, no more creak... although I was drawn to the bbinfinite super spinny bearings, I opted against changing anything. Just about everyone I know with the various BB designs you mention creak a whole lot more than my frame — particularly guys with PF30 shells — so I guess I will keep things as they are until creaks set in or the bike industry decides threaded BB shells were actually a pretty good idea.
