This is getting less relevant since 2010s with general pixel density above 100 PPI on mainstream displays and pixel perfect fonts default. I'm really enjoying the defaults in OpenBSD for a graphical desktop on a 27" display refresh in 2011 after a 17" in 2005 with pixel quality matching the 10" notebook from 2010 on all three displays about 100 PPI. This means, I absolutely disable and do not need sub-pixel anything, neither hinting, nor different than crisp 1 pixel line fonts. Thanks to OpenBSD for providing me the fluent desktop Xorg experience daily.
