There seems to be no stable consensus on which LLM one should have used, to get good results. Which is somewhat natural, things are moving quickly - and evaluation methods are immature (and the little we have, actively gamed).

But a lot of the arguments seem on the surface to be of "No true Scotchman AI" form. Or "you are just holding it wrong" (ref Apple).

I find 4.1 superior to Claude in my few adventures into vibe coding.
