JoJo no Kimyou na Bouken Part 1: Phantom Blood, Sakigake!! Otokojuku Recommendations
Both are inspired by Fist of The North Star. Sakigake!! Otokojuku starts off as a gag manga with it quickly transitioning as a battle series with a very good tournament arc. JoJo's Bizarre Adventure is very horror-based but contains the same masculine tone in parts 1-3. If you like one then you'll more than likely enjoy the other.
Manly men doing manly things. Both are have a somewhat similar aesthetic (for example character designs and line work), gory fights and both draw quite a bit of inspiration from Fist of the North Star.
