For a PF I would recommend an one piece like from BB Infinite or a threaded screw in BB like from Wheels Manufacturing

For PF I would spend the extra money for a one piece or threaded system because it can eliminate creaking, make the bike stiffer, and in my experience with BB Infinities BB86 One Piece GXP Ceramic BB it has been amazing. Not sure how many watts it saves or if that matters but each stroke is insanely smooth. I have BSA on my Specialized and quite frankly I just run the standard SRAM DUB BSA BB at $35 because replacing BSA is so much easier that I treat the BB as a disposable.

If you were picking a bike mainly on BB yeah BSA IMO is better. PF can be fine but it all comes down to manufacture quality and tolerances. I have had no issues with my PF86 BB but I was so freaked out about going PF that I allowed myself to be sold by Hambini and BB Infinite to go BB86 GXP rather than DUB cranks because their rationale is that the smaller bearings of DUB would wear down quicker than the larger bearings of GXP. I have a handful of friends using BB86 PF DUB with zero issues with thousands of miles on their BB. This is all to say yeah there are some more optimal BB standards compared to others but don't get sucked into all these wishy washy engineering blowhards otherwise you will be stuck on a dead road platform like me unless I totally switched BB again
