IMO, (that means "in my opinion",
not "After a 5 year study, Consumer Reports has come to the conclusion")

tabbed window management blows tiling away. Having ran them both pretty hard (though I didn't put them away wet) I can say with some certainty on my part that 'Tabbed' is the way to go. Over 2 years of steady Fluxbox use, and I just can't escape it! I don't want to escape it! Tiling was to me, a pain. All the key-bind memorization, config files, (text or lua) it just isn't worth the effort. Perhaps if I had started my Linux experience with a Tiling WM I'd feel differently. I didn't! And you can achieve just about any kind of 'look' your going for with Fluxbox. It's 'Tabbed' WM features are incredible! I lub Fluxbox!

Everything on one screen, using "Mod4 + Tab" to navigate between the open applications 'grouped' into one window, is just way convenient!
