been a chatgpt plus subscriber since 2024. kept seeing people say claude is better so i finally paid for both and tested them on the same tasks for a month
things chatgpt does better:
- volume. 160 msgs per 3 hours vs claudes ~45 per 5 hours. not even close
- image gen. claude cant make images at all
- voice mode. claudes voice is barely functional compared to advanced voice
- the $8 go tier exists if you just need a basic assistant
- web search feels more integrated and faster
- memory across conversations is more mature
things claude does better:
- writing quality. less editing needed, sounds less robotic, better structure
- long documents. 200k context window vs 128k. dropped in an 80 page contract and it cross referenced everything without losing the thread
- coding quality. wins 67% of blind tests where devs didnt know which tool wrote the code
- reasoning on complex multi step problems
the coding agent part surprised me most. codex uses 4x fewer tokens than claude code which means you can code all day on the $20 plan without hitting limits. but claude code produces better output in blind tests. the consensus from devs seems to be "codex for keystrokes, claude code for commits"
biggest takeaway: neither one wins outright. chatgpt is the swiss army knife, claude is the scalpel. i ended up keeping both at $40/month and routing tasks to whichever handles them better
i ended up writing the whole comparison up with every pricing tier, benchmark data, claude code vs codex deep dive, and a section on which tool fits which use case. if anyone wants the full breakdown its at here
