I personally use awesomewm because I find it's easy to use with either keyboard or mouse. I've not tried other ones in a while so it could just be a case that I'm used to it though. Thinking about it, by "using mouse" I still need to use the modifier key...

By default:

Mod+Left click = move window

Mod+Right click = resize grid (when tiled) or window (when floating)

awesome[1] has pretty decent mouse support, as far as tiling Window managers go.

Windows 10 is pretty good IMO.
