I'm also a beginner but have tried them all,
I prefer the 5500 over the others for the extra AF points, Articulating screen and WiFi.
However, if you go the 3300 way like I did and search for deals, you may find yourself being able to buy the Camera with Kit, and the coveted 35mm prime f/1.8g lens, for below the price of the d5500.
If you have the extra cash and find an okay deal, I'd go D5500 way.
Otherwise, let yourself be a beginner and learn photography on a less expensive D3300 with the 35mm prime to boot.
Good luck.
