having tried 3 of the 5 (kontakt, Halion, exs24) have to say kontakt is the best of them. One sampler is much like another they'll all be fine for techno. I just think kontakt has better filters than say halion, and seems to have a better overall sound engine. But doesn't matter what your making with it. If you want a better sampler look at getitng yourself a hardware akai or emu.
