Don’t like SRAM, for multiple reasons – cranks you can’t take off without a massive allen key and a length of pipe to extend it (you can fit/refit Shimano cranks at the trailside, with a normal multitool and a rock, if you have to).
If you haven’t blitzed your SRAM cranks it with 54nm of torque, then the bolt will loosen fairly quickly, which is a problem if it happens mid-ride.
As above, with Shimano you can shift with forefinger over the bars, not to mention double or triple upshifts. SLX has this. SRAM GX Eagle has none of this, and feels pretty industrial, although some people like this.
Shimano brakes can be a bit flakey, although bleeding them properly helps, and I’ve not heard entirely glowing reviews of the SRAM equivalents.
It has been suggested that SRAM mechs can be a bit easier to kill than shimano, and I don’t think you can take apart and clean up/adjust the clutch as easily.
Having said this, a lot of people have said that Shimano 11 speed isn’t as nice to use as 10 or 9 speed (or 12, for that matter). Avoid the XT shifter – SLX is nicer.
is it not a bit pricey?
Might be worth keeping your eye on the differential – looking only at the drivetrain groupset, SLX 1×11 is 249, SLX 1×12 is 349. I wouldn’t go for 1×11 in those circumstances.

Though obviously you have to add in the price of microspline for your wheel as well.
