Getting mixed reviews on GPT vs Claude

I see people say ChatGPT is failing at basic tasks and starts making stuff up while Claude is amazing and can handle everything

I never had any issues with ChatGPT, I literally use it to parse excel data and read 20-30 pages of existing documents and make one big document with new formatting based on my needs. It does these things flawlessly.

I don’t understand the hate for chat gpt? Can someone share their experience? I’d like to be ahead of the curve if possible, I’m just not experiencing the issues that i see other people talking about regarding ChatGPT.

Is it because I default mine to extended thinking?
