Depends on the problem I think. Opus has been pretty amazing across the bench, but GLM 4.7 is able to compete in most areas. But its SO much slower... I am using lots of Codex 5.2 high right now.
I think the question is always what you are looking for. Opus was great, because it was able to build a proper integration plan from a vague feature idea. But if you take some time to outline the plan more thoroughly and maybe even write some naive code examples / interfaces, GLM and Codex seem to work just as well
