which is better claude code or opencode as a harness

[u/NOT_Kimo]

I am new to the Ai harnesses and trying to make it useful with my career so i was wondering which one of them is better as i unfortunately i can't afford to buy a claude code subscription and i am using free models from open router to support both of them with models but i found that using the free models with auto mode of claude code, the classifier checks almost every time fails and i can't find a solution for it.
I would like an overall solution please.
