• sysvinit with openrc-init
• elogind with seatd

Yes. I run Gentoo.

Doas has a readable config file and it is easier to add an user. To answer your question On an MX install.

Xfwm -> bspwm

Dont remember -> nsxiv

Don't remember -> mpv

Featherpad -> Mousepad

The default terminal (varies) gets switched to Kitty. VLC to MPV.

Okular instead of the default PDF editor (varies).

Text editor (varies) to Vim.

I usually just install Arkenfox, but if I'm feeling lazy I'll use Librewolf.

I prefer doas, but I don't usually switch to it.

I rebind my caps lock key (most useless key ever) to escape.

Bahah as other dude said I don't replace anything cus I'm on arch btw, but I often tend to remove the default web browser whenever i run a vm or somethinf cus base Firefox isn't my thing, its far too dull for me. I rock ff forks like zen browser, librewolf, icecat, and mullvad. Currently on zen.

Found myself replacing the broken file roller flatpak by the file roller from thr APT repo.

The desktop linux feels more and more like windows as time goes on. The things that worked fine for years are being broken in new and innovative ways.

I'm a simple man, I see Brave mentioned in a positive light, I downvote.

KDE Neon - I replace the Firefox deb with the snap.

I definitely do the Firefox to LibreWolf (and also install Brave as a backup). I also replace the default video player with Haruna and VLC (but default to Haruna). I change music players all the time so I just replace the default with whatever I feel like using at the time. In the past I've replaced Thunderbird with KMail, but on my latest install I left Thunderbird alone since I like having available RAM.

I also replace Firefox with LibreWolf and Brave! I don't do much more than that though; I used to replace GNOME Software with Warehouse, but I eventually found it easier to just remove PackageKit and use Software to install my flatpaks (I still use Warehouse for changing flatpak settings).

I didn't see this one yet:

apt -> nala

Though I think it's technically just a wrapper, the colour support and formatting makes things much easier to parse (visually)

I wonder who's even using these built in video players, no subtitle support, barely any keyboard shortcuts, trash like windows media player

I have a script that makes a list of every package and binary into an output file of packages as a list. I can just cat the output of the file in a subshell and pass that off to pacman -S. Pacman might complain here and there, but I can just edit the list. Then its just cp -r my config files that I've backed up and run my backups for movies, music, pics, games, etc.

And yeah, it's not perfect, but it's good enough for me. I still have to do other stuff like switch out bash for zsh, etc. Gotta love bash scripts and backup configs though. That plus actual backups makes restoration from catastrophic failure at least bearable, albeit still time consuming.
