I use i3. It's not perfect, but it's the best I've found. I like: 1) tile movement is very dynamic; it's tree-based 2) supports transparent terminals; I like seeing my pretty wallpaper 3) mod key works well for switching desktops, and moving tiles between desktops 4) good multi-monitor support. I don't like: 1) no dropdown application menu. dmenu is ok, but I need to find a good menu bar app. 2) You can mouse drag-resize, but not drag-reorder tiles. It's on their todo list.
