I want the easiest to configure/theme wm and one that comes with sane defaults. Also I currently use cinnamon, and I’m not sure how to escape from that(everything in it is just so nice) but I want the speed of a wm
If you like the relatively polished experience provided by a DE like cinnamon, you’re unlikely to enjoy a WM. It’s a much more DIY experience. Unless you have particularly unusual window layouts, you’re best off just learning the keyboard shortcuts already supported in your DE.
