Swings and such!

Does anyone have experience with the 4moms swings and rockers? I had wanted a mommaroo... At my shower I got a rockaroo (which is still awesome) and I also got a fisher price rock n play sleeper. I'll be taking one back because I don't need two rockers. Is the rockaroo super great? Should I take both back and upgrade to the mommaroo? Will the fisher price one be just fine? Tell me your opinions and experience please!
