So I finally made my samurai and I think I got all the great lined up. Is the skills the same as fighter or different? I'm on mobile so it's hard to check.

No, Abilities are different.

Personally if I were playing a pure melee Samurai, I would choose 2 Abilities: TwoHitBack (Samurai ability and Blue colour[color]) and Retribution if NOT using Salvation or a healing charm. Otherwise I would use Salvation with TwoHitBack.

Note: using TwoHitBack ONLY works when two(2) monsters (or more) are on the screen, it won't attack if there is only one(1) monster on screen, that is why I selected Retribution, as this ability is like PowerStrike BUT charges up (has a chance to) when you take damage... a 0 damage = no charge up chance (same as Powerstrike when hitting with 0)

Hope this helps.
