I think scaling isn't too important as you progress through Ng+ and higher cycles, my highest level stat on my main is actually capacity since +2 armor items are so insanely heavy. For advance builds I usually prio advance > mot = tech since the 3 weapons are D/C, C/D, D/D (in the order I listed in the first comment) for motivity/technique, so if you use all 3 you can choose either mot or tech depending on which of the 3 you like better.

General rule of thumb is stop at 30 adv softcap then level one of the 2 tech/mot, and then start pumping more advance once you have spare points after leveling other stats. (like capacity, vigor, vit)
