Maybe that Sandies are the best of what humans can provide, but clones are build to fight, no regrets and no feelings, they have been trained to fight since birth, and will show no mercy, and ask no questions, Sandies show they think, but as Obi Wan says in Anh after pasing the roadblock the mind trick only works on the week mind. (sandies are stupid <_< ) They might be the best of the rest and also the coolest outfit in the empire. But Clones show more tactical knowlegde in batle where the TK's, TS's and TD's rush in batle more like old warefare like ww2.
I Love the TD's and have always done that, they are cool and mean.
But never the less they wouldn't stand a chance against Clones.
