Do we need some way to grade these services based on vertical or use-case?

I actually tried the same tech questions to multiple services when I first started playing around with these commercial LLMs. I would copy and paste the same question to GPT4, MS Bing (I soon stopped using that since I already have a sub to gpt4), claude, bard, and recently You (https://you.com) and while Claude.ai was rarely as good as GPT4, it wasn't too far off for tech questions.

I'm not very creative, so maybe the use of it helping with writing fiction or roleplay might help me, I haven't tried it yet.

Did you try Claude with non-fictional tasks, and if so, how does that compare to GPT4?
