Quartersawn and tighter growth rings will be more stable and cut cleaner. Flatsawn, especially if you glue up the full width of the 10" will guarantee that your panel will cup, even if you alternate growth rings in the glue up. If you see wide growth rings, you'll get more tearout/fuzzies (soft wood between rings). If you have no choice but to glue up the 2x10's, rip them into three strips and then do your glue up, but try to not put the same three back together and if possible, try to alternate growth rings.
I recently had a customer, have sent to me, three "butcher block" type glued up 28"x28"x1.5" blanks and they were very stable and cut the cleanest that I have ever seen. Granted, they were of premium tight grain WRC from Perfect Plank in California, but they cut great and stayed flat even after v-carving out three 0.5" deep pockets! Downside is that the color/grain appearance can be rather busy. Butcher block glue up is ripping the boards the width of your desired thickness, plus some for surfacing, and flipping them on edge to glue up.
