Whats the difference between a great 3-4 and a great 4-3

Tom Brady said the most difficult defense to face is a 4-3 with a consistently effective pass rush and cited the giants super bowl 42 defense and the dolphins D in the early 2000's as examples. The current trend in NFL defenses seems to be toward 3-4.
What's the major differnce? does the 3-4 concentrate more on stopping the run?
