This is the reason a #Shimano XT #derailleur costs more than a Shimano Alivio. On the left you have the whole-body slop of an Alivio M3100 derailleur. On the right you have the same of an XT M8000. There's noticeable slack in all the pivot joints of the M3100. There's no noticeable slack in the XT. It feels like a single piece. The result of this difference is misshifts like going one gear higher then back to the desired one, or otherwise some shifts taking longer between gears.

There's a second video in the original post showing the XT derailleur.

Loool I've been telling my self maybee I should up grade to a 9x or 10x. But then I go for a ride and realize. It's more fun to just shut up and ride and not be a prissy over things like fancy parts or weight reduction. Like bro. You are 200lbs on a good day and bike weighs like 40lbs what the hell is reducing half a pound actually going to do for you?.
