IMO it looks worse than X11 core rendering because those fonts are often bitmap fonts made to look good without antialiasing whereas just disabling antialiasing in vector fonts often looks too jaggy. Some fonts have good hinting but the vast majority do not bother. In Windows i also disable antialiasing since i do not like the blurry look but i also force fonts in web sites with good hinting since most sites look horrible with their preferred fonts.
