Upgrading Nikon D3200 to Canon 600D

Currently I am using Nikon d3200, and I am thinking to upgrade my camera to Canon 600D/ Rebel T3i. Is it a better idea to upgrade from Nikon to Canon. Though I can spend on some new lens for my Nikon, I’ve read that Canon has some built-in color enhancement also does Canon 600D have any drawbacks. please advice.
