It is a nuanced point but what is better, a sedan or a truck? I think we are still at that stage of the conversation so it doesn't make much sense.

I do think it is a good metaphor for how all this shakes out though in time.

Yes you use the models for the same things, and one is better than the other for said thing. The reasoning process is an implementation detail that does not concern anybody when evaluating the models, esp since "open"ai does not expose it. I just want llms to to task X which is usually "write a function in Y language that does W, taking these Z stuff into account", and for that i have found no reason to switch away from sonnet yet.
