IMO Stanton is a very good choice, can be set up for whatever you want to ride from XC to DH to 4X and with careful component selection be very good all round.
If budget no issue first off I’d get duel position Lyriks (£650 at on one)
120mm XC 4X then 160mm Trail Ridding/DH.

Crossmax SX wheels (guy on here is selling some her won in an enduro race, brand new £530)
XT Group Set (Ribble had some amazing prices last week if not try Merlin or Rose bike/bike discount de etc)
Renthal/Thomson finishing kit.
Oh yeah and a beautiful LG1 Trail Guide (I’m selling one as new £75 posted RRP £110 😉 )
