My current preference is icewm. It is small, fast and easily customized to one's own tastes. I experimented with most others.
The standard TC wm is small and fast but I found it cumbersome to use multiple windows. Also, cumbersome to minimize and maximize app's. Disliked the grey backgrounds as well.
Ifce and probably lxde are the best looking and easily customizable but I have odd problems with the cursor becoming distorted, which I could not resolve. Similar with openbox.
Fluxbox is small and fast, but once again I had cursor problems and in some cases problems with keystroke detection. Reported but not resolved.
I have tweaked various available schemes for icewm until it looks the way I like. It is fast and no odd problems have arisen thus far.
I continue to experiment with lxde (thank you, bmarkus) but my cursor problems were there as of last week, so no plans to change for now.
TC is a fabulous distro. Now my workhouse for day to day activity.
Best regards,
