Yes, fc20 stands for Fedora 20. The difference between it and Ubuntu isn't that big if I zoom in: http://imgur.com/ptlQEmf

Based on the other comments I got, the small differences could be caused by different anti-aliasing settings or font engines (I'm currently using freetype-freeworld-2.5.0.1-5 for example).

I see, well as a test you could download the Ubuntu fonts and switch to them for comparison.

PS I agree too, they look better in Chrome, don't know why.
