Oh, indeed. Even the newest of the new, ridiculous as they look (except for the eyestalk) are some nasty bits of art...and apparently, they can switch out their weapons at any time, but they're getting to that...which might actually explain some of the bulkiness.
The old ones were definitely cool, but when I think about it, they were probably the most...vulnerable, so to say. Victory of the Daleks shows the Doctor whacking one of the 2005 editions with a crowbar,with virtually no harm done to it except for getting a little flustered. But in Remembrance of the Daleks, his companion Ace whacks an Imperial Dalek with a super-charged baseball bat until its eyestalk and dome fall apart! And that's just one example! In another episode, they whack off the eyestalk like a twig the shove it out a window!
But, on the other hand, they managed to build their own edition of the TARDIS in The Chase, which made for a cool episode.
Why they've never done it again, I don't know.
I'm guessing that in the old Who-New Who encounters preceding the upcoming Asylum of the Daleks, those little Old Who mutants must have squelched up in terror at their superiority!
