Two of my bikes are Shimano, the third is SRAM.
Having being a fan of anything that isn’t Shimano since 2005 I have to say that SLX and XT are a very pleasant surprise…they’re nicely clicky and TBH they’re maintenance free, distant memories of mech and shifter barrel adjusters are thankfully just that.
My X9s though feel agricultural, they won’t engage top gear without careful timing of the shifter and the ergonomics aren’t perfect. I do occasionally shift with my trigger finger when weighting the bars.
Not surprisingly, I have a set of XT on order for bike no 3.
