The chaotic AUR singlehandedly makes Arch great (on weaker machines).
I use EndeavorOS (99% Arch) and I haven't looked back. Up to date software, knowing what's in my system, minimal bloat, but I would recommend Fedora or openSUSE to beginners and intermediates. I can't recommend Ubuntu or Manjaro. Using either one of those is like signing your sanity away.
Fedora and Arch are very different. That's like saying openSUSE and Fedora are the same, even that's not as extreme as your claim because they at least use the same package format.
Getting more performance is not greedy. What is greedy is adding hacks for performance for $$$'s which is greedy considering the security nightmares that come with it. Also, how the hell are you supposed to update your BIOS if it's not supported by fwupd and you can't use Windows?
Also, what Zen 3 added was not flushing what Zen 2 flushed.
Maybe CPU manufactures shouldn't add hacks to their CPUs for more performance, and therefore more $$$'s. If they were held liable this'd never happen.
Do you know why Zen 2 and Zen 1 don't have this issue? Because they didn't come up with the hack they used to increase performance (and therefore $$$'s) back then because they knew it'd leak like crazy. This time it didn't seem like they cared.
As someone who's used it for at least 3 years, go for it. However, it requires lots of configuration to get it the way you like it, so openSUSE Tumbleweed is probably the better pick for you.
It also comes with cool utilities like nvidia-inst (archinstall advocates, write that down) and the community's great too.
Trojans that install themselves into the MBR will just screw up your boot process on a UEFI system and vice versa. Also, if you don't use a default bootloader, you'll definitely notice something on a UEFI system if it tries to delete all other bootloaders.
On BIOS systems however, it gets a little tricky, since it just blindly reads the first few sectors, without respect to what you "set" as the default, so that Trojan could just add itself and move everything over a bit, and you can't tell. See the Michelangelo MBR virus. It wiped your drive on March 6 of any year.
On a UEFI system, the best it could do is replace the Microsoft bootloader, and that would trip Secure Boot, which is enabled by default. Even then you don't need to directly modify sectors or format your drive, you can just replace the bootloader.
Yes, yes yes. As a person who's used EndeavorOS for at least 3 years, if it breaks, it's because I broke something, (like accidentally deleting my DE), not because my apps went to dependency hell.
Yeah, don't even touch Manjaro OR Ubuntu with a 100 foot pole.
openSUSE Tumbleweed is what I'd use if Arch stopped existing, TBH.
