If neither Orthodox (EO/OO) nor their splinter groups, then probably Roman Catholic (traditionalist or sedevecantist). If not RC, then it'd be a toss-up between Pure Land Buddhism, Baha'i, Zoroastrianism, and Sikhism.
I feel a bit differently now, and not so apt to jump the Christian ship.
If I weren't EO or OO (nor their related groups), then maybe I'd be a Melkite Catholic, followed by other Eastern Catholics (preferably those with more of a sense of their patrimony/autonomy and less Latin dependency). After that would probably be a more traditional Old Catholic (e.g. PNCC) or Anglo-Catholic Anglican, otherwise a Latin Catholic of the FSSP variety. The Assyrian Church of the East would probably be in there somewhere too.
I guess I'd be primarily interested in being part of a more conservative church with a more traditional view of the Eucharist.
