The others have already answered the basic this spell vs that spell question, but I wanted to weigh in on CC in general.
Don't forget using root as a CC option. Typically longer time a mob can be locked down per mana than a mes.
Also, the mes/calm/re-mes til blur/let the unwanted add walk away trick is great. Works very well with the L4 mes because it's basically no mana.
For example, when I was feeling saucy Clr duo'ing in HS and I'd pull 5-10 mobs at a time with my charm pet eating the HT's. As they pile on I'd stand behind the pet, color slant, and I could mes/clicky/fetter before stun wore off. 2 CC's per stun, backing off the pet.
Back up, rinse, repeat. There were times I had nice little lines of 10+ merbs in a row waiting their turn to get raped by my pet.
For King groups specifically, I'd be calm blurring adds off whenever I could depending on the group's DPS, and only mes'ing casters. But I hate Sebilis. So you'll probably never see me doing that
