Nope never have, or never noticed. I like the way they work and they are easy to bleed, also can be found cheaper than just about anything. At least in states.You've clearly never had the bite point randomly changing to behind your grip feature Shimano are famed for.
I'm not kidding.
Yeah.Everyone's different.
I have Shimano on some bikes, SRAM on others.
I'm neither a fan or a rival supporter of either
