One thing I do when using Source Code Pro is shorten up the line spacing a bit. There's a slider to do it in iTerm2, and you can use these options in Sublime Text:

>> "linePaddingTop": 8,

>> "linePaddingBottom": 8

By default that family of fonts almost seems double-spaced to me, otherwise I really like them.

It is surprisingly hard to obtain a consistent font rendering across OSX, Windows and Linux. I had to play with the weight of the fonts, but also the font size (on Windows, my font is 3pt smaller than on OSX...). Irritating, especially when you actually synchronize your configuration files.

I agree, and the main irritant has to be OSX and its refusal to do any hinting or 'sharpening' at lower point sizes. I hoped the retina will make it better, but amazingly, it doesn't quite enough, fonts still look too fat and rounded on the edges!

Thanks for that tip. It really makes a difference in readability.
