Yep, a 4x4 is definately taller. I wouldn't be without one but I understand the challenge. My buddy has a 2WD RAM and it's definately a little easier to get into. Seems like you need running boards for either, though. I have good ones and have no trouble stepping up into mine.
I wouldn't beat anyone up over 2WD vs 4WD. There are definate advantages to both.
