I was using Gemini and Claude quite a bit over the last year, mostly with pro or opus for planning and flash or sonnet for implementation.
MiMo is the best one I've used so far, but I haven't done anything interesting with the Claude 4.7 models.
It seems conservative with generally good "instincts", getting things working quickly without too much complexity.
I've also embedded it in several different projects so far, and it's been pretty easy and effective.
My plan was just upgraded to 38 BILLION tokens per month. That's at least 10X the tokens I've used in my entire agentic development so far.
I should probably downgrade my plan, but we'll see. :)
