The Ghillie has the advantage of being customizeable for the conditions , but the price is weight(about 4 lbs) and they're hot . They're better suitedto paintballIMO.
I shoot in a 3-D leaf cut suit , no snag problems so far . It's a little noisier than the Ghillie , even after repeated washings , but much more comfortable to wear. It doubles as a bug suit , and when it's warmer you can even wear it by itself and enjoy the breezes .
