I find devstral (even though it’s weak generally) much better at writing and documentation than Opus. I’m actually now delegating all documentation to devstral and away from Claude, which makes a mess.

A highly skilled carpenter may be able to 'get work done' by banging nails in with a heavy-bottomed cocktail glass, doesn't mean it's not painful to do so when it is continuously breaking and leaving shards of glass all over the workshop for you to find every day for the rest of your life until you clean up the mess you made using the wrong tool for the job.
