the leaders before the non leaders, the ones with high SA multiplier before the ones with lower ones, the hard hitters before the ones who hit less hard (For example, as great as STR SS3 Vegeta can be, it is unwise to waste elder kais on him, even in his time of glory, same for int janemba).

The ones with % attack boost before the ones with flat boost (except for ridiculously powerfull ones, like LR Broly and Bardock) and as a final criteria, if you have 2 or more dupes for a unit with supreme damage like PHY SSGotenks or SSB Goku, it is recommended to give them the kais to profit from the bottum right path.

And of course it is more prior for your main team, for example, FP Frieza is in all measurs worthy of the elder kais, but if he's your only good Extreme Phy unit, it may be better to make him wait
