There are differences in ecclesiology implicit in the differing rites, but both are obviously orthodox. Further, variation in rite is more the historical norm than absolute ritual uniformity. So,  the two forms are perfectly capable of coexisting under the mantle of one church.  I would not reduce the difference entirely to "taste"  although the presence of variations in form of Catholic worship in not nearly the matter of spiritual life of death that many "worship warriors" make it out to be.
