Crankset opinions

[truebeliever]

Hey,
I'm currently exploring options for a new crank set. I'm currently running a XX crank with 39/26 rings. My coach is pushing me hard for a power meter and with stages discontinuing their x9 crankarm. I'm currently looking for a new set up.

I'm looking at the m980/985 with stages and the m9000 with stages but am curious to see if anyone has had any problems with 11spd cranks and 10spd drive trains.

I am kinda stuck using a double because where my local trails are, the terrain is quite flat and the larger ring is needed.
any help would be appreciated greatly

No difference between 10 or 11 speed rings, and cranks themselves are certainly no different.
