For what it's worth, I just went down a full size, but my new boots are easier to get on than the old boots. The drop in size is partly due to losing some weight and partly due to some improvement in the swelling of my left ankle. The latter MAY be somewhat related to weight, but is primarily due to an old injury to my left calf. Both the old and new boots required some heat adjustment to open up the curve of the tongue.
So anyway, in side side-by-side comparison, my brand new, adjusted but not even broken in Tecnica Ten.2 are easier to get on than my old Salomons, even though my foot was swimming around in the old boots, and the new boots are a little stiffer. Pulling up on the tongue loop helps a LOT on the Tecnica, much more than it did on the Salomans.
