I am in the process of making the canonical switch into the Maronite Church. All my paperwork is in, we’re just waiting to hear back from the bishops.
I did actually consider switching over to Orthodoxy (Antiochian Greek Orthodox to be exact). The biggest thing that kept me from doing so are many of the internal problems with Orthodoxy - problems such as nationalism, the lack of visible unity and various internal schisms, and the lack of willingness to address Western Christianity on its own terms rather than trying to force Western Christianity into an Orthodox mentality.
The biggest issue that I’ve had, I’d say, is the papacy. Although I’m not as much of a “papist” as many Roman Catholics would want us to be, I also don’t believe the Orthodox have sufficiently responded to the papal claims.
That being said, the Orthodox are fully Church and possess the full means of salvation. I long for the day when Catholics and Orthodox are again one, but I think that it’ll take a direct intervention from God to make that happen.
