Anyone level Director Krennic/Death trooper yet?

I'm only lvl 81 so no zetas yet my dt is g8 and dk is only g7, the only place I haven't used them yet is in arena, my problem is I can't decide who I like better for lead, dk potency and the ability block to debuffed enemy is nice, but so is palps health/tm gain, so without any zetas which do you guys think makes the better lead?
