I have had SRAM Rival 10 speed on various bikes since 2011. At the time, I thought it was miles better than those shitty 5700/6700 groupsets.
Ergonomically, it’s pretty good, although the hoods are a bit small and chunky. The double tape is great, the chainsets are great, the rear mechs are perhaps a touch flimsy, the front mechs are great until they stop working for no apparent reason, the BBs are average, the brakes aren’t quite as good as Shimano.
Shimano stuff is good except for the shifters which are hateful. The 6600 series 10 speed stuff with the exposed cables was very smooth, but theres something about the brake levers that makes them difficult to use. Must be the pivot location or something; I have big hands aswell. I don’t think they’ve improved it for the 11 speed stuff either.
You’re best off with Campag Ultrashift though; ergonomically superior to all. Multiple gear shifts in any direction; separate paddles/buttons for up and down shifts; loads of front mech trim positions that actually work; very well put together. Plus you can strip it all down and clean/rebuild if needed.
