I started out with a D90 and it suited me well, but you have to be willing to learn a LOT about cameras if you want to maximize it's potential. Judging from your questions here, I don't think you've done a lot of research on the cameras yet, so that might be soemthing to consider.
Both cameras take good pictures, and both cameras can make "pro" pictures, it all depends on you. For portraits, both are equally well suited when coupled with a nice lens.
Handling is entirely subjective. I love the feel of my D2H, but it weighs in at 1.2 Kilo's so I can imagine some don't like the handling very much.
Visit a store, and handle the cameras in your price range. Don't be tempted to go for the most expensive camera, also consider getting a cheaper one, and spending the remainder of your money on an extra lens, a bag, and perhaps a photo course.
Just keep in mind: a pro camera does not take pro pictures, that's your job as the photographer. Much of it also lies in postprocessing, so don't neglact that as well.
