> haven’t actually used Fable or even Opus 5 yet

I've used plenty of Opus and Fable. Still do.

> Sol is laughable by comparison

Not really, it depends. Sol is better and useful in some areas. Definitely not all.

Fable is gimped just by those "guardrails" that silently downgrades you to Opus 4.8. Not only do you pay extra for Fable but your caching can be easily messed up. It also doesn't just find all the bugs or is bug-free. Sol has spotted lots of Fable issues and vice versa. Fable also costs 2-100x as much.

> I don’t constantly swear at and call stupid

That's not a judge of anything. There are models that may be stupid and you can swear at it, but if they still get the job done for 1/10th the price... maybe that's all you're paying for.
