I only tried a tiling WM for a few days several years ago. I am ok using the terminal but not everything can be done easily there. In the screenshots of people setups, there are always fancy terminals. Are tiling WM good also for other GUI a part from terminals?
TWM resize your windows automatically as you create windows or move them around. This is the key: TWM’s work best with applications that work well in a variety of sizes. Usually this means text based applications: terminals, IDE’s, browsers, chat apps, etc. GIMP for example didn’t really work well for me unless I used it on its own workspace. It comes down to this: how much of the time do you use text based applications? For me, that’s almost always. I rarely touch something that is not a terminal or a browser. For you it might be different. Good luck.
