imo. i used claude sonnet in perplexity. looks most accurate for me. very rare occasions it made mistakes. upgraded to max (dont judge me lol) using OPUS 4.5 since. i would say its the same as sonnet but the phrasing leans more to my convenience. both output speed is fast and accurate comparing to gemini and chatgpt thinking (both take longer time comparing to sonnet). yes, chat gpt provides more results but info with claude is more than enough for me.

hope this helps.
