Shimano Claris 11-28 have a slightly better jump than the SRAM 11-28, see below*.
Get the Spa Cycles for one reason - the square taper mean you can try and get the shortest bottom bracket possible for the low Q-factor, I managed 107mm with the double crankset with a couple millimeters of clearance on the arm despite recommendation of 113mm, the fact it's 165mm mean there's a little more clearance with the chainstay and thus might be able to push it down to 103mm.
The Hollowtech one as great as they are, have one fixed q-factor.
