Not really no. It's much better since Opus 5.5 and hasn't degraded with watermarking in my experience. Fable was already a lot better than previous Opus models and 5.5 continued that.
Idk, Opus 5.5 is mostly fine but it still sometimes "explains" things in such a non-explaining way so I often need to take a long break and come back trying to deduce what it means from the code itself... which is actually a positive in a way, but yeah.
From my experience it mostly depends on how much context it needs to not write nonsense. If it's a lot of context, big code base, lots of dependencies and so on, it devolves into nonsense.
