Better than Finaplix?

I recently came across a different product from a vet store that carries Finaplix. Its called Component T-H and for about twice the price($70), contains about twice the TA(4g). While the two products are equal in this manner, I was wondering if anyone knew exactly what the difference is. Both conatin TA, but perhaps Component T-H may be easier or have less binders to hinder the absorbtion or quality.
