I hate sram. But I have xx1. It's good. Really good. Shifting is light and crisp.
I'll third that
I wanted to go with the grip shifters but so many people have been having issues and I didn't fancy being without a working drivetrain while waiting for replacements which might then break again.
Fortunately the trigger shifter is really nice. Initially I missed the two way finger release but now don't notice. With a small matchmaker clamp on to Shimano brakes the bar is quite clutter free too which is always good.
The main bad point (which hasn't really materialised in to anything too bad so far) is the wider cassette challenges the chainline of my frame, especially when in the biggest cog. The chain looks a bit strained but it seems to work ok. No option to move the ring inboard either as I don't have the clearance between the ring and chainstay. I guess what frame you have makes quite a big difference here
