The new renderer definitely looks better, but the letters still have something fuzzy about them. They don't feel crisp. Is this due to the font or due to the rendering?
The fuzzy is just an artefact of parts of the font not lining up with the monitor's pixel grid. There are ways to deal with this, but they can distort the font in other subtle ways, so no solution is perfect.
In any case, it makes much less difference (almost none practically speaking) on hi-dpi displays.
One of the reasons web designers have issues with text looking different between Windows and MacOS is that Windows' font renderer tries to force things to align with the pixel grid more, reducing a sharper result but slightly distorting some font characteristics. Apple's renderer is more true to the font's design, can can produce a little fuzziness like you see here. It also makes many shapes look a little more bold (at least on standard-ish DPI displays). A couple of old posts on the subject: https://blog.codinghorror.com/whats-wrong-with-apples-font-r..., https://blog.codinghorror.com/font-rendering-respecting-the-.... Differences in sub-pixel rendering also make a difference, so where people have tweaked those options, or just have the colour balances on their screens set a little differently (intentionally or due to design/manufacturing differences) you might see results that differ even further for some users even on the same OS.
