I would suggest that you reverse those roles. gpt-5.5 as the implementer and Opus as the reviewer.

They find different things, and there's no reason to use one model for review. You want to review it until there's nothing left to be unearth.

And if you put the review effort into polishing an impl plan, then it doesn't matter which model implements it either.

How come? I find Opus to have better taste and GPT to have more rigor.
