I'm gonna have to go with the first one.
Although it has lower combat stats, overloads would ease its training to higher combat stats. If you'd rather not drain HP, voila! - extremes.
Also, the right-hand stats (mining down) are very nice for dungeoneering.
If you don't mind raising another *near* maxed melee, the first account would definitely be my choice.
Couple your combat training with dungeoneering, and you'd have a good general account on your hands.
