In regards to tools, you can usually find a distro that is "batteries included", try KDE as your DE - There's great tools like Okular, Dolphin... Insomnia is a pretty looking Paw alternative etc, however I think the advantage with Linux is that you can often build it how you want, without the junk that is there and you don't even know what it does, but it consumes CPU cycles. Moreover, with distros like Arch Linux, you get practically all the available tools, always up to date, never have to reinstall, updates take a minute as opposed to half an hour and you can mange everything, (not just brew packages), with an awesome package manager.
I really don't want to say "MacOS > Unix" because of any reasons i mentioned. I also had ArchLinux as main OS on my Desktop, and also tried a new KDE Flavor.
But for me personally it was never as good as MacOS. Maybe i wasn't trying hard enough, or don't want to loose any spent $ on MacOS only software. Dunno. Anyway i just hope for myself that i can get a great MacBook again ;)
(What i missed the most on MacOS was always a fast and keyboard focused window manager like 2bwm. In the end i was able to recreate this behavior with hammerspoon and some custom lua scripts in combination with alfred. MacOS just looks sometimes a bit bloated with all these rounded egdes, drop shadows etc.)
