That's really great news. I always wondered why text rendering in Chrome looked so much worse than Firefox.
Linux is a goofy with this too, but still looks better than Windows. macOS handles it best on high-DPI displays, but because subpixel anti-aliasing is no longer used, fonts can be a little blurry on low-DPI displays.
On the other hand, back in Mac OS X Leopard, the OS lets you adjust the level of font smoothing. I preferred the strongest level of smoothing. Many designers hate that because it is akin to faux bold. I didn't like that Apple removed it in Snow Leopard. These days it hardly matters though.
