I still prefer Firefox.
It has been YEARS of putting up with the horrible Google font rendering in Google's browser on Windows, all the while IE and Firefox render them perfectly.
Linux's fontconfig allows for all sorts of configuration. Ubuntu, by default, probably has the nicest config. Otherwise, I personally turn off all hinting but leave subpixel rendering on. Brings it closer to what OSX does.
Personally, the best font rendering I've ever seen is on a high PPI Android phone. Most pages that are more than 2-3 paragraphs I forward to my phone for reading, since my desktop displays aren't that great.
Chrome[1] seems to not do any anti-aliasing, as opposed to Firefox[2].
Of course, a lot of people have complained that DirectWrite rendering is "fuzzy", so to each their own I guess.
I've been starting to use webfonts and this issue has been very annoying for me (as a Linux user, where pretty much all fonts look good).
