Here’s a summary of my brake experiences through the shop:
Avids — PITA to change pads as the pistons don’t like being pushed back and often difficult to get sensible lever travel
Hayes — faff to change pads and push pistons back on older brakes
Hope — horrendous pivot wear on older levers
Shimano — very occasional leak issues but nice to work on, rapid pad wear in sloppy conditions with older brakes
Tektro — levers can be easily accident damaged but no other problems
If I was buying brakes for myself they’d be either Shimano or maybe the lightweight offerings from TRP (the posh wing of Tektro).
