The last one is ok, but I like thinner fonts. MS fonts are legally available on Linux (just accept the license). I know that may be blasphemy to some, but here's how fonts look on my system:
If anyone cares:
$ sudo apt-get install ttf-mscorefonts-installer
$ cd /etc/fonts/conf.d
$ sudo rm 10-hinting-slight.conf
$ sudo ln -s ../conf.avail/10-hinting-full.conf .
$ sudo ln -s ../conf.avail/10-sub-pixel-rgb.conf .
$ sudo dpkg-reconfigure fontconfig
