There are some very deep divides between the two religions you are contemplating. Just one will define your choice, so if it is the religious belief that you are interested in, that one point is all you need to make a decision on.
Was Jesus, literally, God incarnate, who lived, suffered, died, and arose again to pay for humankind's sins? Yes or No.
If it's a social community you are interested in, then you need to determine which offers the best fit, but I must warn you, neither will accept you for conversion without the "belief conviction." Yes or No.
Good luck!
