I have Claris 2400 on my gravel bike. Its 2016 Specialized Diverge. The only thing I'm not a fan of are the cables sticking out of it. I have over 1000 miles on this groupset and never had any problems with it so far. It shifts pretty smooth. It is 2x8, so gear jumps are larger, but you get used to it once you build up your legs. I am planning on possibly upgrading, but I'm not in a hurry yet. I don't compete or race, so there is no need.
