*Stat gains on level-up are not random, so no need to soft-reset every level if you're a min-maxer.
*Over 31 levels, each Attitude offered +8 to each stat it boosted. For example, with Logical, the SPR and SPD were each 8 points higher than with Grouchy (an Attitude that doesn't boost those stats). Conversely, with Grouchy, the HP and ATK STR were each 8 points higher than with Logical.
*Single-stat boosting Attitudes (like Brainy's "SPR+") just do double work. In other words, over my 31 levels, my Brainy Frostail had 16 more SPR than a non-SPR boosting Attitude (that's +8 x2). By extension, the Brainy (SPR+) Frostail had 8 more SPR than a regular SPR boosting Attitude (such as Logical).
*The inherent stats of the Yo-Kai DO NOT MATTER for Attitude. You will gain the exact same amount of SPD from a SPD-increasing Attitude regardless of whether your Yo-Kai is naturally super-slow or super-speedy. This means that you can compensate for weaknesses easily using Attitudes.
*Even HP gets the same amount as the other stats. This is imbalanced since HP is generally a higher number than all of the other stats, so I would avoid HP-increasing Attitudes for min-maxing purposes, such as Grouchy (HP/ATKSTR), Helpful (HP/SPD), Gentle (HP/SPR), or Tender (HP+).
*Not all Yo-Kai can have every Attitude. Those with damaging Techniques cannot be Gentle/Tender (as those are for healing Techniques), and those with healing Techniques cannot be Logical/Brainy (as those are for damaging Techniques). Those with ally Inspirits cannot be Twisted/Cruel (as those are for enemy Inspirits), and those with enemy Inspirits cannot be Helpful/Devoted (as those are for ally Inspirits).
