Linux

I used StumpWM for many years. It was great for most of my workflow and, being written in Common Lisp, you can recompile parts of it while it's running (I didn't do this often but it was a cool feature).

Sway with autotiling and a few nifty scripts (launch or focus and such) and Waybar. The combination of having scratchpads, sensible autotiling along with titlebars and the wonderful world of wayland is supreme.

I've been very happy with hyprland since it's the only Wayland TWM that allows a great experience with nvidia.

I don't

herbstluftwm - because it just works and does not try to think for me;

The configuration is a shell script using herbstclient to talk to the wm process, that's a plus for me, too.

This is perhaps cheating, but after diving deep into the hardcore tiling mangers (ratpoison, wmii, xmonad), I grew softer and stayed in awesome for a while, but eventually I realised that since all I want from tiling anyway is the ability to quickly place two windows beside each other, I might as well go with a DM that does all the other stuff I want automatically (mounting, monitors, etc.), and since KDE is now good again, and coming along on the tiling side, that's the tiling WM I'm using.

Yes, I said I was cheating ...!

I'm using sway on top of fedora. I heard positive things with i3, but I wanted to try something that was native wayland.

I use i3, but to say that I like it is a bit overstated. It's fine, does what I expect the very basic of a tiling window manager to do. I used Nimdow for a while and it's pretty good, the default bar is way better than i3 (supports ANSI colour coding, mouse presses, etc.), but I could never quite get to grips with the tiling algorithm.

I'm working on my own WM though, it's not tiling per-se, I choose to call in non-overlapping and I'm trying to solve my gripes with i3. Basically windows should not be forcefully expanded if they don't want to. Try open galculator under i3 and watch the horror. And when expanded the size should be split based on their initial sizes. So if I have Firefox open and want to do something in a quick terminal window the terminal won't get 1/2 of the screen. Firefox wanted more space than the terminal initially, so the terminal gets to take up a smaller share of the space.

I'm on Hyprland (wayland compositer, wl-roots based). Prior to the wayland transition I was on dwm. Hyprland offers a dynamic tiling layout just like dwm, which was my main selling point. The dev is very active and hyprland is gaining maturity rapidly (more than alternatives like dwl or river did at the time I checked it out). I also tried i3 and sway, but they don't quite cut it for me as they don't do dynamic tiling out of the box.

I used suckless ecosystem for 5+ years, but I wanted to use Wayland so now I'm transitioning into Sway and holymoly how fast and easy it is. So simple to configure and written in C.

Currently using sway, but mostly for the lack of good Auto tilers on Wayland
