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.
