When it comes to Windows on ARM, so many reasons to pick a Windows laptop over a Mac are thrown out the door by self-sabotaging compatibility in that way. It's just not a good experience in my mind, unless you plan to use your system like a Chromebook and just stick to browsing the web or using other basic apps.
I would also say that 12th generation Intel is more competitive with Apple's current silicon than it gets credit for. It beats Apple on single and multi-threaded performance. No, you won't get 20 hour battery life, but you can find a respectable balance, and to that point I don't think it's worth making the ARM tradeoff on the Windows side of the house.
For Apple, ARM is great because they're betting the farm on it. For Microsoft, ARM still looks like a bit like a side project to me.
