You should note that the Nemetrix is a grade-A knockoff that has many differences from the Omnitrix.

For one thing, the Nemetrix can't be used properly on humans or beings of the sort, only on lower-intelligence aliens like Khyber's Dog.

Should also be noted that the Nemetrix only contains nonsapient aliens.

(I would note bugs, like when Khyber's Dog was randomly transforming and even attacking Khyber, but it's not like we haven't seen a ton of bugs out of past Omnitrixes.)
