Linux PhpStorm users out there: What fonts do you use?

On a stock Ubuntu install, the default font used looks very thin and jaggy and no matter what font we tried, it always looked strange.

Eclipse is WAY better in that regard (which is understandable considering they are using SWT and thus native font rendering).

What font or even top secret jre parameter would you recommend for the best possible look under Linux?

Personally, I'm working on a Mac where it's looking awesome (and also using the native font rendering due to apple doing some magic), but I'm asking in behalf of a coworker who is using Linux.
