Personally, I have owned them, and I used the prototype offerings of the Quantum XT and Quantum II, too, but I never liked them. So, to
me, their value would be rather low. Yes, I know they can work okay for some people and in some locations or applications, but for me that wasn't the case.
In our more mineralized NW Oregon soil, and some even worse that I hunt in Nevada and Utah, I got better overall depth and general performance from the modified Classic III SL or modified IDX Pro or 6000 Pro XL/XL Pro units or the XLTs I had at the same time. They have a more defined sweep speed requirement than the others and if swept just a bit too fast or a bit too slow, performance dropped off. I'm just giving you my results with two models against an assortment of other detectors I had and used at the same time.

I guess that depends on what makes/models you are used to using, the search coil that is mounted, and the rod-length of adjustment.
I have used all of the White's SL line of detectors, including all of those I listed so far plus the Classic ID and Classic II SL and DFX. Yes, they can 'feel' a little heavy, but mainly when using the 950 search coil, and really poorly balanced if you have the rods extended too far.
I keep rods adjusted so that when I am standing erect in a search position, the search coil is positioned roughly 18" in from of my foot.
Also, with all of the models mentioned, I only used the big 950 coil when I was searching the open ocean beach or a wide-open sports field or large grassy park lawn. My favorite search coil with them, as GoGoGopher mentioned he uses, is one of the 6
