Which Warrior Explorer Trains Fastest after 150?

Well, title is a little misleading.

Only want the choice to be between Hero and Paladin [Sorry Drks]

I got 1h fafnir axe and 1h fafnir bw. Both fully scrolled and both got relatively same potential.

Basically these two classes will have identical equips. Paladin seems pretty decent training [it's what I have currently] but he's only 110ish. I've heard great things from my hero friends.

SO just wondering which be best to aim to get to 200 fastest. Changing classes isnt a problem since I have the mesos for it.

Thanks~
