I was baptized Catholic in infancy, although neither of my parents were practicing Catholics. I was in the Orthodox Church (mostly in the Serbian Diocese of Western America) from 1990 to 2003. I then reverted to Catholicism.
Why did I convert to Orthodoxy? They believed everything that I believed, or at least everything that I wanted to believe. I was skeptical of the powers of the papacy (although I even then realized that the popes since Pius IX at least have all been good and holy men, and they all probably will, in my opinion, ultimately be beatified if not canonized). I fell in love with the Divine Liturgy and icons and the veneration of the Mother of God, as well as praying the Psalms. Also, the priest who converted me was young (a convert from Pentacostalism, although he was part Greek) and very personable: his kindly wife was a former novice with the Little Sisters of the Poor and they had four extremely endearing young children. I felt more at home with them than with my own family: I saw myself as a young aunt or older sister of the children. (This priest later converted to Missouri Synod Lutheranism and became a pastor in that denomination.)
If there had been an English-dominant Byzantine (or Ukrainian, Melkite, Russian, etc.) Catholic parish within 10 km of my house at the time I was considering conversion to Orthodoxy, I might have switched over to them and formally changed my rite within Catholicism. Although there is now a Melkite Catholic mission (with a largely Arab congregation – about 50-60% of the Divine Liturgy is in Arabic) a couple of miles from my house, that was not the case when I was converting to Orthodoxy. (I am more of a Slavophile when it comes to the Divine Liturgy, however

But the nearest English-dominant Eastern Catholic parishes with a Slavic background were at least 20 miles away from my house – a prohibitive distance for me, since I do not know how to drive.)
