The SOTA models now work really well in my codebases, but that's only been since Opus 4.5/4.6-ish. Prior to that, and with current local models, they simply couldn't work holistically and would just thrash around. Now I feel as if SOTA are approaching my coding levels if not surpassing it. I still need to guide on architecture, but I can see that going away within the next year or so as well.
