When doing some rebuilds/component swaps, I decided to try the new Shimano calipers for the easier bleed port access and increased brake pad clearance. Both of these things are improvements over the past series of calipers.
I also upgraded a bike with Ultegra-level GRX levers and calipers to the new generation of Ultegra brakes, and I think the servo wave tech on Ultegra is actually worth the hype. If you want to save a few bucks though, these brakes are solid.
