The Paladin's 5e CD is actually better then the 4e CD, except its daily resource instead of encounter. Actually making the 5e CD encounter based instead of so many times a day would be an improvement.
A Cavalier can use his CD to heal (Lay on hands), Smite, or turn undead, the Warden can do the same thing except he switches smite for Natures Wrath which deals damage and creates difficult terrain, and the Blackguard who can use his CD to Smite, Unlease his Dread Aspect, or Rebuke Undead.
All are useful, but the down side is you get 4 uses of CD max.
In practical terms the Paladin will get more use out of Deadly Strike as its at will, but almost everyone gets it and its flavourless, and thier Auras which are not a daily resource. Plus your mount at level 8.
Honestly I'd trade Deadly strike for something more flavourful and Paladinish, maybe something linked to your Oath.
