I think you are missing the point here. The only 3rd party constant app I* use is Conky. All else is just built in to KDE. However the big question is, after seeing the numbers people have posted, how can you still be harping on "efficiency"? KDE is NOT inefficient. When one considers it's capabilities, it is in fact amazingly efficient. When one considers that it is possible to enable or disable services galore to suit your hardware and workflow matrix, again the point becomes entirely moot, as it is a matter of taste.
KDE 4.3 is long gone and was never ready for actual use. Anything above 4.8 is flat out awesome. So please stop dredging up the past. Xfce4 is a great DE. So is KDE.
BTW considering "snappy". If you want snappy above all get a 3.8GHz P4 box and run Windows 98, or better, WFW 3.11, or for that matter, Slackware v9 or 10 with a trimmed down kernel, or even eComStation! That's snappy! but at what cost? Just how much can you do on them?
Finally, to answer your last question directly, that depends entirely on the user. In my case, KDE provides an excellent, indexed desktop search that I use regularly, and I can't say enough about the power and versatility of KRunner. Dolphin is simply my preferred File Manager. I am entirely happy with 6% CPU idle and 600MB ram footprint. At even double that footprint I would still have almost 7 GB of headroom. That's more than sufficient. It's luxurious.
