Same, Shimano 105 hyd with stock pads. Over 1,000 miles through rain, gravel, mud. Only time they've squealed is during a hard braking effort in the rain, but not during normal use. I clean the bike thoroughly after gravel rides, and then clean the rotors with alcohol just to make sure nothing is on them. I haven't had to do anything with the pads. I did have a piston get stuck on the front rotor, but it was replaced under warranty, no issues since. I also routinely swap between my gravel and road wheelsets, no issues with rubbing or adjusting. But I run the same rotors on both wheelsets because I didn't want issues with adjustments when swapping. Hopefully when I get my disc road bike it is just as trouble free.
