I'm in love with Meslo https://github.com/andreberg/Meslo-Font works great both on my iTerm as well as in TextMate. What makes this font special is the L/M/S variations in the leading (line height). Give it a try, you won't regret!
Other than that it is a welcome improvement to Menlo regular.
Eclipse has its lines of text set-solid which is seven brands of evil, so the "M" version of Meslo is a godsend.
