As long as you will have powerful windows desktop or use cloud services to render bigger final images, you will be fine.
Contemporary Intel and AMD laptops are roughly 2X faster in multithreaded rendering, but they only got that fast in last year, before that, M1/2 architecture decimated everything.
Also, the big Windows workstation laptops are heavy and loud machines, while Macbook is beautiful, still very thin thing.
If you want to get Macbook, get Macbook. It's not purely rational decision, you need to enjoy working on the machine and if your heart is set you would just be dissapointed by else.
