The skills are similar, but longboarding has a very different feeling in the ground contact with the board. It allows for better pumping and carving, which has created disciplines and skills that have differentiated from skateboarding. If you like one, pick up the other!

In my opinion, longboarding is more about enjoying the ride and the time on the board, while skating is more of enjoying what you can do with the board.( such as fliptricks, grinds, etc.) very similar, although id say longboarding is more of a peacefull feeling, while skate boards are kore for adrenaline rushes
