I would say stick with i3 unless you are really a fan of lisp. I used StumpWM for years until I discovered i3, however a few months ago I switched back to StumpWM. The floating layer in stump is quite frankly terrible. Pop up dialogs often act oddly. Yesterday I was updating ebooks in Calibre menus were appearing full screen and the progress dialog would grab focus and pop to the front on every tick. These are the types of issues that caused me to stop using it 4 or 5 years ago so unless you are willing to fix them yourself I wouldn't count on things improving. That being said I much prefer the StumpWM tiling over i3. The tree structure that i3 uses is a bit odd. Stump is much more straightforward you have frames and windows. Windows are displayed inside frames and you can split and resize frames however you like. I never have to focus parent in order to split a frame vertically instead of horizontally as you might in i3.
