well I can't speak for the 700 but I got the 620 for Christmas and I love it! the swivel screen was must for me as I had a nixon coolpix with that type of screen before! it takes awesome pictures, the night vision feature is awesome! I've gotten many a great dusky picture (see my layout called sleeping... that was taken inside a tent at 9:30 PM!) Sorry I couldnt' compare, but I love my new camera
edited to add..with the batteries.. I can easily get 150-200 pictures per a set of batteries. I have rechareable ones and they work great!
