The Scooby Gang and Angel Investigations are dumped into the Supernaturalverse and decide to become hunters. They face all of the same monsters and villains that Sam and Dean did. They will receive help from Bobby early on and Castiel if they survive to Season 4 and beyond.
Meanwhile, Sam and Dean are dumped into the Buffyverse at the beginning of the series, and deal with all of the monsters and Big Bads there. They will receive assistance from Giles and access to the Sunnydale High library, and whatever stuff that Giles might have laying around his home.
Which team does better?
