after a few hours use, my impression is that Opus 5.5 writes like gemini. drastic improvement over all opus 5.1's claudeisms.

and i think i was generally more tolerant of 5.1's writing style than most people.

I think you mean Fable 5.1 here. Fable 5.1 was an improvement over Opus 5 but still had many Cludisms. Opus 5 was insufferable.
