If you talk to enough people, and enough fitters, one thing that becomes obvious is that different peoples' feet fit different brands and models of boot differently, and that there is no such thing as a good choice for everyone. Oddly enough, that seems to be true even for custom boots. Also that getting the right fitter matters at least as much as getting the right brand and model.
And, for some strange reason, even some people with very good fitters, who do all the "right" things, end up with boots that don't work for them. I don't completely understand why that is true. However, to some extent, they are not precision crafted, and aren't always made to the desired shape. In addition, I suspect current foot shape measurement techniques aren't as good as they should be.
The only boots that fit me fairly perfectly were the Riedell 220's (old style, single leather thickness - the newer Riedell 220's were much stiffer) I bought at Play-It-Again Sports - my first pair of skates. They shouldn't have fit, as I have completely the wrong foot shape for Riedells - but were flexible enough to mold to my feet anyway. Of course, that flexibility doubtless played a part in the leg I broke... I tried once another pair of single layer leather boots (Risport dance boots, which were almost new), but they broke down in about 2 or 3 weeks - apparently, though I'm not a very good skater, single-layer-leather isn't good enough once you have fairly deep edges, which is one thing my ice dance coaches had emphasized a lot (they said the side or top of the boot should brush the ice, though I never quite got there consistently, except in crossover and progressive underpushes), despite my other limits. Apparently, you have to accept relatively stiff boots to avoid rapid breakdown if you edge much, not just if you jump.
I've gone back to my mostly broken down 12 or 13 year old Klingbeil custom Dance boots, because they are finally somewhat comfortable, and because I don't jump enough for the relative lack of support to matter. Every once in a while I have to re-stretch the boot near the toes and ankle bones, and make myself new insoles, probably because they were fit wrong by the wrong custom fitter/skate tech, and because I didn't realize that you can take custom boots back to the manufacturer and get them re-done right, when they are fairly new.
My experience with other types of shoe has been much better. I can make do for a long time with fairly cheap tennis shoes, as long as they fit in the first place, and provide a fair bit of support. (Though the very cheapest tennis shoes did break down once I started going to the gym much.) But I don't edge normal shoes much the way I edge skates... I make my own custom-fit insoles for them too, which plays a major role in making the fit better, and my insoles cushion impacts better. My XC ski boots and hiking boots never wore out, though in retrospect they fit poorly, which contributed to numerous ankle sprains.
I didn't like the Coronation Ace blades I bought first, but that may be because they were warped - sold to me by the same fitter/tech who misfit the Klingbeils.
I switched to MK Dance, and loved them.
I switched to Ultima Matrix I blades (the ones that had the interchangeable runners) some time ago, because, the were cheaper MK Dance, and because I thought the idea of quickly switching between freestyle and dance blades sounded cool, though it turned out to be harder than I thought, because the bolts are trouble prone. When Ultima stopped making them, I bought a sufficient number of runners (several Dance runner pairs, as well as a Supreme freestyle pair, and a Synchro pair, as well as some extra bolts) to last me the rest of my lifetime. It took me a long time to get used to the different shape Ultima blades had, but I am sort of used to them now.
Anyway, it is wonderful that you (TropicalSk8ter, the o.p.) are fairly happy with your current boots. Some people never get there.
