Claude
The one to pick if your work is long documents or code; for casual chat the free tier is fine and the paid seat mostly buys headroom rather than new abilities.
Pros
- Long-context handling is the reason most people switch to it
- Same models reachable from chat, desktop app and API
- Free tier is a usable product rather than a token trial
- Annual billing brings the Pro seat down to $17/mo
Cons
- Pro usage limits bite during sustained coding work
- The step above Pro is $100/mo Max, a five-fold jump
- No image generation, unlike most rivals at the same price
- claude.ai blocks automated access, so scripted use has to go via the API
