We Have both. I wanted the bouncy and some one got us a swing. We used the bouncy when he was really little allot actually. His first few days home he would only sleep in the bouncy seat so it was honestly a blessing. When he got a little older we used the swing more often. It did not get as much use as the bouncy but it held him in better when he needed some "chill" time to calm down. It really depends on what your baby prefers, which for us was the bouncy.
