Kind of flipping the thread on its head but i think two things Cyberpunk does (much) better than the Witcher would be its prologue and gigs.
White Orchard and the wider Velen opening story of Witcher 3 I found so dour and uninteresting I abandoned the game not once but twice. Had i not known its reputation as one of the best games ever made I'd have refunded it because it simply was not interesting, showed no promise of becoming interesting and was not enjoyable. It was stereotypical peasants being miserable, an almost unfathomable control system, annoying monsters and trees. (It doesn't help that the very opening scene is porno Yennefer, which does not predispose a player to like the game if they are not in whatever that target market is supposed to be.)
I felt Cyberpunk did a much better job of dropping you into engaging material.
On gigs, I simply didn't like most witcher contracts.
I disliked the mechanic of having physically to go to a notice board and then pick them up, amassing the equivalent of a work to-do list. I disliked having to read the encyclopaedia to prepare. And I disliked the fights which, with some notable exceptions, were not narratively interesting. I'd sigh every time I went to do one and eventually stopped bothering. Basically, they felt like Cyberpunk's cyberpsycho jobs: formulaic.
Cyberpunk's gigs felt much freer in how they could be played and more varied.
