^The Dual Shock 4 has better features, but I am going to have to tell you after Christmas because I am going to wrap it up and give it to myself, I mean my son for Christmas.
Dualshock 3 had a lot of "flaws" according to fans, stuff like triggers have supposedly improved. I saw no major problems with the other one, but I'm always happy with improvements as long as they're not ridiculous.
My PS4 I ordered for myself though ALL the Disney Infinity stuff I've 'gotten for my son for Christmas'... That's a different story, Lol. He'll be excited I am sure, but I just can't wait to play 2 player with him!
