In KDE my favorite is an extension to the window manager, for auto tiling: https://codeberg.org/anametologin/Krohnkite or install it from Settings > Window Management > KWin Scripts, then click “Get New” and search for “Krohnkite” by anametologin. Development is a bit slow at the moment, but it does the job well.
I like that there are different layouts available, meaning different logic how a window should be placed and sized. I can switch between layouts on the fly. Every virtual desktop can have their own layout by standard, in example my fourth desktop is always untiled like a normal desktop. Exceptions to specific windows or applications to not tile them can be added too. So the usual stuff. It comes with some features not seen in other tiling window managers. In example I can convert any window into a “Dock”. A dock would then be always at the edge or screen, similar to the KDE bar; basically making the screen area to tile windows smaller. Super cool.
Edit: Rephrased a bit to make it more clear and added some more info.
