GS III vs. Nexus 4

I got my GS III a little over a month ago. I had issues with TouchWiz at first, but after rooting it with CM10, I fell totally in love with it.

But now that the Nexus 4 is out, I'm doubting myself. I love the ability to stick a 64GB micro SD into my SIII and carry my entire music library without putting it on the cloud, and I appreciate the 4G. At the same time, the screen is sometimes excessive for my taste and I'd love to have a stock Android experience without rooting. Plus, I love the design of the Nexus 4.

Is this just something that everyone feels when a new flagship comes out? Or is selling my GS III and getting the Nexus 4 not that crazy of an idea?
