Pressfit BBs are all garbage, they always creak, they use plastic pieces to allow greater manufacturing tolerances, and if there's a problem with the frame there's nothing you can do, you can face it but you can't fix it if it's slightly too large or elliptical. Comparing pressfit BBs to pressfit headsets is full retard, take both apart sometime and think about how the two things seat and why it's different. My hardtail and full suspension bikes both have around 4k miles on them, the HT has a threaded BB and the FS has a PF30. Obviously if you ride off road you have to service your BB a lot, especially if you ride in the wet. The hardtail I unscrew the BB, grease it, put it back in. The FS I have to tap it out, grease it, press it in. The threads can withstand this indefinitely, the pressfit is an interference fit so every time you have contact dragging in and out of the shell, and unavoidably the BB will change angle ever so slightly and damage the shell in a small way, but it adds up over time. On top of all this, pressfit offers 0 advantage, other than cost for the manufacturer.
