I prefer Menlo/Deju Vu Sans Mono. It's amazing how all these monospace fonts differ in rendering between, say, 10pt and 18pt. I often find that the best looking one at a larger size just doesn't have the right 13pt/14pt sweet spot where it's both elegant and functional. The rendering also differs between systems, and even between frameworks, so there's not even one right answer.
It's my (self-appointed) job on HN to also remind people that if they love Inconsolata, but hate the curly quotations, you can get straight-quote Inconsolata-dz.
I didn't even notice the curly quotes until you pointed it out. I guess today I'll either decide I don't care or get maddeningly frustrated and download Inconsolata-dz :)
I had to stop using Inconsolata because when it is a pixel or two wider when bolded (by Eclipse or other editors). Perhaps I installed it wrong on my Ubuntu machine, but I couldn't figure out how to fix it.
It seems to make the gap between lines enormous in Emacs. Is it just a configuration issue? (compared to Deja Vu Sans Mono) I can't accept a font change that means I can fit less code on my screen and have to read smaller text to boot.
