The verdict
Both ChatGPT and Claude are solid choices if you mainly want writing & content, business & teams — for those needs you won't go far wrong either way.
Choose ChatGPT if your priority is good at everything, image generation, voice conversation.
Choose Claude if you care more about coding & development, long documents & analysis, privacy-conscious.
Both offer free tiers — the genuinely sensible move is to try each on a task you actually do, then pay for the one that earned it.
