So the thing with Debian and any Debian based distro like Ubuntu or Linux Mint is there is no big centralized software repo like the AUR. Yes there is the apt repository but if you want something that’s not in there, get ready to read the documentation or follow random guides.
For example, one of my friends wanted to download an audio tool called Reaper. On Windows this is just looking up the application and clicking on the .exe. It really depends on the dev if they include a .deb, sometimes you might need to download the .sh file or they may tell you to compile it yourself. Perhaps, you have to add a ppa. On Arch, all I have to do is Paru -S Reaper, if there are multiple Reapers I can look for that by typing Paru Reaper.
Now that Arch is so easy to install with the Archscript, and the software repo so vast and easy to use, is Debian really user friendly if you have to jump through several hoops to download programs?
Edit: yeah yeah there’s flathub and stuff but that’s more of a last resort, optimally, you want to get it the correct way.
Yeah, slow app launch for one thing. Lack of DE integration for another. Flatpak apps are so completely foreign elements in the distros I’ve used that I have no inclination to use them.
And the few times I’ve had to use on, it’s so bloated with redundant dependencies. I understand that flatpak apps will share dependencies within their ecosystem(?) but since they’re the exception to the rule on my system it never becomes a benefit.
Besides, as is OP’s point — I have the entirety of the AUR at my fingertips. Why would I bother with anything else?
