Agree 100%. And I also work a lot on lower level / systems stuff (including RTL here and there, too). Opus is sloppy, and leaves negative cases all over. The GPT models in Codex have a more pedantic and detail oriented "personality." Often to a fault.

Sol will leave a mess of excessive redundant tests and isn't so great at abstraction ; but it produces more reliable working systems.

It's kind of nice to have access to both, but I don't have the $$ for that right now, so I just keep the Codex sub
