I had a F800GS before and have a Tiger Roadie now. If you are looking for something very flexible for all types of roads from highway to back road to gravel or fire road, the Tiger is the way to go. If you are looking for a monster dirt bike, the F is better in my opinion.
But that's my opinion, best to ride them both, they are different enough that you'll know quick enough which one you like more.
