hs shaft adapters vs inserts?

Hi, I’ve seen a few discussions on ease of insertion for the adapters vs. the inserts and was planning on using the adapters as they ship with all the newer gears and wheels. I’m finding though these seems to have a lot more slop / play. E.g. twp gears mounted on the same 1/8" drive shaft using inserts can be rotated 8-9deg or so relative to each other. That pretty much doubles using the adapters. Wondering if anyone had any opinions on this. I’m guessing most applications it doesn’t matter, particularly if using sensors for auton driving for example.

Thanks
