> Fonts and UI rendering look awful on Windows compared to macOS, there is just no comparison. I've heard a number of people say this, and I'm always puzzled because it is exactly the opposite for me. Running on the same hardware (late 2013 MBPR 15"), Windows 10 font rendering is much more pleasing to my eyes. When I boot into OSX, the text looks terrible to me. (I'm still running El Capitan - has text rendering chan…
I am no professional in typography nor have I used any other Mac than the Macbook 12" (2015), but putting it side by side with my Acer Predator Z35 (35" curved screen), I still like macOS' text rendering a lot more. Maybe it's the fact that it has a huge resolution on a 12" screen. Seems very likely that the higher pixel density makes for a crisp and beautiful text. Again, I am not a pro in this area. I am a programm…
On other words, given the same physical text size on each monitor, your MacBook is using more than eight times the number of pixels to render each character.
Given a choice between macOS on a 226 PPI monitor and any other OS on a 79 PPI monitor, I would definitely prefer macOS too. :-)
You're right that the best way to compare font rendering is on the same monitor for each OS. I wouldn't use 27" FHD monitors though. Those would have 81 PPI, about the same as the Predator.
In my case I'm comparing OSX and Windows on the same hardware: the MBPR 15" (220 PPI) plus a ViewSonic VX2475SMHL-4K 24" 4K monitor (187 PPI) rotated to portrait mode. I'm a big fan of smaller high-DPI monitors like this. 187 PPI is a reasonably close match to the MBPR's 220 PPI. Both Mac and Windows look nice on each of these displays, I just find I like Windows better of the two.
Here's a spreadsheet I've been maintaining that lists the pixels per inch for a variety of machines and monitors:
