I have two bikes: 50/34 11-speed double with a PG1170 11-28, and a Rival 1X with a 42T and an 11-speed XG1150 10-42.

The 11-28:
11-12-13-14-15-16-17-19-22-25-28

The 10-42:
10-12-14-16-18-21-24-28-32-36-42

The only shift where I "feel" the gap is that first 3-tooth jump on the 11-28, from 19 to 22. In a perfect world, that cassette would go 16-18-20-22, instead of having just a single, solitary, 2-tooth step.

I've honestly never once been bothered by the cog spacing on the 10-42.
