Ask HN: $50 monthly budget, which coding models would you recommend now?

I currently have a claude pro monthly subscription ($20) which I use for coding. It's been useful but I'm fatigued from optimising my work around it's session limits. There are so many choices and providers out there today but hard to get a good signal about what's good. I'm not looking for another Opus-level model but something reliable enough that it can follow TDD well.
