If you like using the mouse alot and you’re more comfortable with clicking than yeah there’s really no point in using a tiler.
I disagree with this. I use keyboard shortcuts for moving my tiles and switching desktops but otherwise I use the mouse. I have found great value in using a tiler, not having to manage windows or having them overlap is awesome.
Worst of all, just setting up a tiling environment is a nightmare. You have to configure the actual compositor/WM, which tools you want to use with it (bar, launcher, screenshot tool, notifications, screenlocker, etc) and configure all those too, ideally with some basic theming to make them look coherent. But inevitably you end up with missing functionality especially in the modern area where an app might be sandboxed or expecting all xdg-portals to be implemented, which most compositors don’t do.
Khronkite is worth checking out in relation to this point. It requires minimal setup (keybinds + choosing tiling layout) so it’s a good introduction to tiling WMs. I’m guessing more experienced users would prefer more control but I like it just fine.
