Tried using everything that isn't Claude and I keep switching back to Claude because even the smarter models give me uglier code, or miss common sense requirements. (And the dumber models give me code that doesn't work properly).

I keep trying to switch to something else but I keep coming back. (Typically after a few days of giving a new model an honest go, and finding myself constantly asking Sonnet to fix its output... Yes, even Sonnet wins on this front! They really do have some kind of special sauce.)

I'm not where most of their money comes from though, and I don't know how universal my experience is.
