I would have to say its more for the additional benefits of the other part of the gem, not so much the stamina. For instance your chest is 3 gem slots, a red and two blues. the bonus is +12 stamina (120hp)for having the correct gems. and we will say you are a JC. So in the red slot you put the +10Agi/+15sta gem.(150hp) and 2 Solid Dragon's eye (+51). (1020hp).

Now same scenario. except this time you are forgoing the bonus slot yes, you get 30 more HP (whoopie!). Better chance to dodge, and an increase in armor is much more effective than 30 hp imho.
