My opinion...
The Roman Catholic Church "Mass" is hidebound by tradition. This can be seen particularly well in the "Hosanna" (I"m not sure of the real name). In the Bible, the people were excitedly and happily shouting "Hosanna in the highest" while Jesus triumphantly entered Jerusalem on Palm Sunday. In the Catholic Mass, it sounds like people are reciting some funerary prayer, mournful and sad.
This I noticed when a teen - probably on a Palm Sunday when that passage is read from the Bible.
Make no mistake: the "traditional" Catholic Mass is beloved by many Catholics and also very attractive even to many non-Catholics. But it's not the sort of ceremony that is attractive to me, and you are obviously also not attracted by it.
Before you "jump ship" and convert to another sect, I recommend that you explore options - hopefully with your Catholic pastor or some other advice. For example: most larger cities have at least one Catholic church that holds "charismatic" religious services, and those are very much more like what you experienced in the Non-denominational church.
In my experience (I've attended Sunday services repeatedly in about 20 different churches), non-denominational, United Pentecostal and Assemblies of God all put on a sort of "show" for the audience. Modern, loud music (much too loud for my tastes), lively sermons and other activities that keep the audience riveted and interested. This is not necessarily a bad thing!!! But realize that it *is* show, and that there is far more to a church than how entertaining or interesting or personally-involving the Sunday service is.
So: explore your options carefully. Don't make any sudden, ill-informed decisions about switching churches. On the other hand, I highly recommend that you explore religious services in as many local churches as possible. Don't neglect your Catholic obligation while doing so, though! If you call it quits with the Catholic Church, do so knowing - not hoping - that you are making the right decision, a decision that allows you to better serve God.
