Really hardly any difference btw the M3 pro & M2 pro versions. Battery life is practically the same for the 14". Was looking to trade in the M2 pro considering the hype going around the M3 chips last year, but looks like there is no need...

No thanks, I've seen the discolouration and scratch prone effects for all Apple's space grey products over time, from iPhones, iPads to MacBooks.
Even with their new chemically treated anodisation, it still won't stop those problems. Not to mention their new space gray is a much lighter tone compared to previous space gray.
