It's got to be shimano for me, at any price point they do fantastic brakes Deore's do the Job admirably, but I've had great experiences with LX, XT, Saint (older 2 pot and currently XTR (with old style XT levers)…
Mix and match compatibility of calipers and levers and spares/Pads availability is actually pretty good (find me a shop that won't carry/order in shimano parts)
Hope are all well and good, I like and own some examples of their Hubs and BBs but I don't see the additional value in their braking products over and above shimano's not when your looking at almost double the spend in some instances for something that arguably does the same job no better (personal opinion only of course)…
If you choose to express your patriotism through the products you buy then I suppose that's a big plus for Hope, but otherwise go with the masses…
