I haven't been using the service long enough to comment on the quality of the responses/code generation, although the outages are really quite impactful.
I feel like half of my attempted times using Claude have been met with an Error or Outage, meanwhile the usage limits seem quite intense on Claude Code. I asked Claude to make a website to search a database. It took about 6 minutes for Claude to make it, meanwhile it used 60% of my 4h quota window. I wasn't able to re-find it past asking it to make some basic font changes until I became limited. Under 30 minutes and my entire 4 hour window was used up.
Meanwhile with ChatGPT Codex, a multi-hour coding session would still have 20%+ available at the end of the 4/5 hour window.
