What's the most powerful land unique unit in your opinion? 

Comanche Rider with Blitz-Autocracy-Imba-Tenet upgraded into a Giant Death Robot.
edit) anyone who says Camel Archer or Keshik is a noob.
It's easy: Pracinha. It's far more powerful than every unit listed here. I.e. Pracinha against Battering Ram? Ownage.
Are you saying the Khans aren't fudgingg awesome? They're the other reason the Mongols are as powerful as they are.Should've included Carolean in your list, probably the best UU from the warrior line.
Still my pick is Keshik. Its really the only thing Mongolia has going for it and its still considered a pretty good civ, that should be enough proof that its a good unit.
You mean the Huns...Battering rams are crazy, especially if you haven't been paying attention to the Mongols and they end up sneak attacking your cities with at least 6 of them.. T_T
