Many Linux distros are good, distro choosers help. But imho, for OSes and especially Linux distros the importance imho is the following.
DISCLAIMER: I don't condone distro wars. Whatever you have probably works, this is just my personal opinion.
a) FOSS (otherwise it ain't Linux). Helps in auditing and to spot bugs faster.
b) Secure (if it's compromised, what are the risks? is it frequently updated and/or stable?).
c) Highly customisable - freedom! Being able to pick "Windows/Mac/other" looks is just one part of it. Being able to modify more parts helps for your user case.
d) User-friendly - works out of the box or installs only what's needed, no bloatware. Accessibility settings.
It also depends on how well you know Linux and how to deal with computers in general.
Let's include non-Linux:
F-tier; Uninstall that shit
Windows - paid, proprietary, bloat- and spyware.
Red Star OS - filled with DPRK spyware.
E-tier; Also don't recommend
Macintosh - much more usable and secure than Windows, but that's it. Very propietary and commercialised.
Red Hat OS - too commercial.
D-tier; Your choice, but could be better
Ubuntu - stable, mainly useful for servers, and beginner-friendly. However, it hogs a lot of resources and isn't as secure or private.
ElementaryOS - very beautiful and MacOS-like, but somewhat commercialised and should improve in terms of security.
C-tier; Has its niche great usage
QubesOS - best for security imho together with Arch. It's not user-friendly, but if you care about safety from an OS being seized... it's also good in combination with Whonix.
Whonix - Debian fork, focused on security.
Tails - best for privacy, you'll need to shut down the computer before restarting though.
NixOS - manages packages very well. The leadership is problematic, so I'd [recommend Lix and/or AntiX instead.
B-tier; Good all-around, but fits specialists better
Debian - adheres well to the core principles of Linux, very stable to the point of lagging behind.
Arch Linux - arguably the least nonsense, but it's not very beginner-friendly, though has a lot of help guides.
A-tier; Beginner-friendlier, smaller issues
Linux Mint - "it just works". Still has some proprietary and small security concerns, but specifically for people new to Linux, especially when coming from Windows, I would actually consider this to be above Fedora Linux.
Fedora Linux - generally user-friendly, has great security too. Actively developed by a FOSS community, though Red Hat-backed.
S-tier; Hallelujah
OpenSUSE Tumbleweed - German, has excellent security, good for sysadmins especially. User-friendly installer and has a lot of customisation.
