I like Linux Mint it resembles windows a lot, like
@Captain Holly said, but the devil is in details. It took me two weeks of fiddling to get Evolution and Libre Office looking like Microsoft Office. Downloading the office icon pack and installing Windows fonts helps a lot, but there are small differences, which can be very annoying because it nearly is the same but different (e.g. going back an indent after an unordered list or continuing an ordered list with the next number after a break, e.g. because you put in an image). And as
@Oldie1950 says when you know your way around, why change (don't fix what ain't broken).
Security wise it (Linux Mint) is very strong with flatpak sandboxes and the ability to AppArmor services which are allowed (e.g. printing) to be touched by the programs inside the (flatseal hardened) flatpak sandboxes. I run all applications in flatpaks and only what was installed with the distro as system. So my next Linix project would be to switch to an immutable version.
That said I have to agree with
@Victor M security wise Windows may be worse than Linux but it can be easlily improved with free utilities (e.g. SAC or WDAC-ISG and blocking risky file extensions with SRP or using Defender's cloud whitelist). Also (as my dear friend
@UltimateVision often states), when home users would run standard user, there would be less infections on Windows.
