Coby white or Jonathan isaac?

I’m only considering using them for salary cap. Fo all diamond premium players (non hidden gem or gems of the game) have the same chance of having a low salary cap every refresh of salary for each player, or do better diamond cards like lonzo have a higher chance of having a higher salary?
