i did SFK till 20 and that was nice and ez with good exp, 2 pulls to clear 99% of the trash

then i moved to SM, GY gave me really low exp, i did cath, and that gave me a great amount of exp.... if you are inside the church, and u pull the main boss (forget the pallys name) it will pull the rest of the place, making it so u dont have to run around and pull all the trash in there
