No, I haven't, at least recently. I switched to tiling about 7 years ago, tried a range of WMs (dwm, ratpoison), stuck with awesomewm for several months, but as it was changing to Lua-based configuration with too much of a flux, I left it for xmonad. Two things that immediately struck a chord with me were multi-monitor support and sane keyboard shortcuts. This post¹ may add something for you.
I learned of spectrwm only recently, it clones xmonad's UI, but is more practical (written in C, ini-style configuration vs Haskell code, doesn't need GHC installed). Painless switch for an xmonad user.
i3 already does multimonitor pretty well, iirc, and I don't have multiple monitors yet. Also, I really like i3's keyboard shortcuts. So I'll stick to i3 for now.
Honestly, I think i3 is probably closer to dwm than any of the others you mentioned, and I kind of like it for that. dwm goes a but too far with its configuratiob system, but i3 hits the sweet spot. I want my WM to work, and get out of my way: I have enough things to tinker with.
Although, if I'm ever convinced to go back from tiled managers, I may try sawfish. I do love lisp...
