Not like customizing it takes much time, to get tiling/snapping in any wm/de is pretty simple and takes less than 5 minutes, along with setting up themes/icons and any configuration files for the wm of choice. And once it's done then you're done and don't have to bother with it any more.
Maybe if you know what you're doing and know exactly what you want... there's no way I could start with, say, a full Debian installation and choose a window manager, panel and other software that I need to set up my own DE and have them all configured to my liking in less than several hours, polishing the setup is going to take even longer. Even though I can tell when I can work in an environment, I frequently fail to miss some little details of what exactly I like about it and what makes it useful (I don't do UI/X design), result of which is an environment that seems good at the start but as I use it, I grow progressively unhappier with it over the days and when I finally after a week or several get fed up with it, it's back to google and a tweaking session which goes on for another few hours.

Used it full time for about half a year with F15 (soon after it came out), and I've been using it on and off now on Ubuntu for the last couple of months. There are quite a few things I don't like about it - clicking an application icon switches to an existing instance instead of launching a new one (on the same workspace that's still fair enough even though I still don't like it, but when it by default switches to another workspace on which I have completely unrelated work it just drives me crazy), extensions frequently break after updating (and apparently even that is still in beta), the notification bar at the bottom is annoying (I frequently hit the corner by accident, causing it to pop up, and sometimes it's got a huge list icons for notifications for events that I don't give a hoot about but can't dismiss all at once), it's still an ass on multiple monitors (workspace previews for example only show primary desktop), and there are numerous annoying customisability issues (such as no easy way to get rid of the accessibility icon for which I have absolutely no use). Those are the ones off the top of my head - I'm fairly certain that if I now went and used it for a bit I could come up with plenty more.
Anyway, I've got Mageia 2, Scientific Linux and LMDE install media on me... I probably won't be needing any OS suggestions any more. I'm going to try out some "exotic" WMs (xmonad to start off) on my Ubuntu installation before I wipe the setup.
