I've been part of many different kinds of churches: evangelical, reformed Protestant, Episcopal, Orthodox, and Catholic.  And the Catholic Mass is the best liturgy, possibly because of its simplicity.  It can be high or low; medieval music or a Gospel choir; totally plain or loads of incense.  It's still the Mass.  That's one of the most "catholic" things about it.  It's the only one liturgy I've never gotten tired of.
