Does shanks have any fighting skills not just because he is an emperor. Is there any proof of shanks fighting ability's i mean how would he fair against white beard in a 1v1 situation...

Btw..Is Fairytale a good anime? should i watch it if i normally watch action anime like One piece,DBZ,Souleater,Air Gear, Naruto, D-grayman.... based on my taste should i give an anime like Fairytale a try?
