Do rockshox and fox have the same crown offset on all their forks...
I thought they did until I stumbled across this...

Nope, while some of the overall offset is in the axle dropout in the lowers, the different offsets are achieved with different CSU (Crown Steerer Unit) offsets like you've pictured.

At least that's been the case with the 2018-onwards Fox and Marzocchi forks I've had. There's different lowers, but that's just to allow for different wheel sizes so you don't have a 29er arch height on a 26" dirt jumper.

Does the one on the left creak more than the one on the right? Being offset would create different forces on the CSU.

The one on the right is for 26" wheels or "reduced offset" forks for 27.5 wheels, so it could be argued the reduced rollover would make it more likely to creak... :p
