Shift quality MIGHT be fine, depending on the cogs you are using.
In my case I used a-
12-28 (12-14-16-18-21-24-28) and a-
13-26 (13-15-17-19-21-23-26 and made a-
13-14-15-16-17-18-19-21.
All but the largest 2 were from "alternating" cassettes.
I think the 1 tooth increments made the shifting "spiffy".

Any shifting problems you see would probably be where you were using wider increments.
