normandy of italy?

[Hooahguy]

im planning to take a trip this summer to either normandy (too see the D-Day sites) or italy (to see roman ruins).
ive done a lot of research on both, and both will cost about the same, but now it really comes down to what others think about the places. none of my friends have been there, so im turning to you guys. (i want more input than just what the tavel sites tell me)
so where should i go? im planning to stay for a week, me, my dad, my brother and my grandfather.
many thanks!
