For straightforward coding tasks I use gpt-5.3-codex on high or xhigh. Sometimes I try 5.5 but overall 5.3-codex is more than capable enough for most of my needs and quite a bit cheaper. For more interactive/discussion/planning or orchestration stuff, I find myself going back and forth between Opus 4.7 and GPT 5.5. Still not sure which one I prefer.
