Qwen 27B for planning, Qwen 35B-A3B for execution?

My 32GB unified memory setup runs both, though 27B even with MTP is something like 7-10 tok/sec. Usable but not real time by any means. (~18 tok/sec with 35B-A3B)

Would it be worth using 27B to plan long horizon tasks, put together the PLAN.md, and have 35B-A4B iterate over it quickly? I can't load both models together, so I'd swap once the plan is set.

Right now I'm using the latter exclusively but am wondering whether the differences in intelligence are as pronounced as some here say.
