Yes.
Episcopalian has some church hierarchy (bishops, etc.). I don't think that Baptists have a church hierarchy. There is a Baptist hierarchy within the church consisting of the Pastor and selected Deacons; however, if you are refering to a hierarchy within the denomination, then no, there is not a Baptist hierarchy.
Baptism and Communion
2 and they are holy communion & baptism
There are many differences. The two biggest differences are in the sacraments of Communion and Baptism. Churches such as Methodists, Lutherans, Episcopalians, and Presbyterians baptize infants and receive communion anywhere from once a month to every Sunday. Other denominations such as Baptists, Nazarenes, and other Evangelicals, receive communion less often and only baptize older children and adults.
There are no greatest. Everything is equal in God's eyes.
You have to be baptized before you can partake the communion.

Baptism, Communion, & Confirmation.
Catholics accept sprinkling baptism across the board. Some protestant denominations do as well, such as Lutherans, Methodists, and Episcopalians.
Episcopalians and Anglicans are closely related but not the same denomination. Anglicans are part of the global Anglican Communion, while Episcopalians are part of the Episcopal Church in the United States. Both share common roots in the Church of England.
The Communion of Saints consists of all the baptized Christians on earth (the Church Militant), the baptized in purgatory (The Church Suffering), and those in heaven (The Church Triumphant). One enters the Communion of Saints through the Sacraments of Initiation which consists of Baptism, Confirmation, and the Eucharist. Baptism is the initial entry into the Communion of Saints.
