both os's are equally as good, i've come to conclude. years ago i used apple computers -- 2c, apple 2, then the early macs, even a kpro, then windows, then more current macs, so i've been through the wars. but as of today, the rmb and m3 surface pro 4, os and win 10 are on equal ground.
That's your opinion.
I've just spent £1,400 on a new PC gaming build and £500 on a 4K LG 27" monitor (with a USB-C connector for use with my rMB, too). None of those products are Apple products, so I have no "warped view" of Apple. I recognise what they do well, and what they don't. High-end computing, as of today, they do not do well at all.
Personal computing, however, they do better than anyone else in the market. Having not used Windows properly for several years, I assumed they would be on a par by now. That's simply not been the case for me.
One thing that
really made me wince was the fact that the official, clean Microsoft Windows 10 download I used from microsoft.com came with pre-installed with a few demos and games. I mean, what is that? They were all easily uninstalled through the Windows store, but that's the kinda thing sketchy manufacturers pull - not MS themselves. It's just not premium, at all. It's
still the poor man's macOS, I hate to say it.
Perhaps there's an element of "what you're used to". Either way, it doesn't really bother me because I just boot my PC, run my games / Chrome, then switch back to macOS for anything else. But there's no way I could make the switch to use my new Windows 10 PC as my main driver (gaming aside), despite it being far, far more powerful and capable than our top-end 5K iMac.
As fisherking said - pick your OS, then pick your hardware. Surface != rMB in any shape or form.
And that's my opinion.
