I switched to quilts 10 years ago, and I have a Katabatic Chisos 40F, and an Enlightened Equipment Revelation  10F.
I was aware of the down shifting problem before purchasing each of these quilts, and asked each manufacturer to overstuff the down. In each case the manufacturer refused.
The Chisos  is used mostly as a summer quilt, and it has horizontal baffles. In this case it can be quite useful in warm temperatures to shake the down to the sides in order to leave the top less insulated for a more comfortable night. Conversely on a cold night I grab the edges of the quilt shake the down to the center before attaching it to my pad. This is very easy to do, and if I don’t move around too much in the night the down stays on top. I have used it at 30F, albeit with extra clothing worn too.
The EE is a cold weather quilt, and has lengthways baffles, and the down shifts towards my feet.  However the really annoying feature with this quilt is the fact that they purposely left a half inch opening at the foot end of each baffle into the next baffle, and the down then finds its way out of the baffle altogether.  Despite EE posting a video demonstrating how easy it is to move the down back by gentle wafting, it doesn’t work anything like that, and you have to move a solid clump of down to the gap and try to pull bits back through. This takes hours of work, is very frustrating, and is hardly a trail task, and I curse EE almost every time I use the quilt for creating such a feature, and having refused to put sufficient down in in the first place.
