Well, some popular manga websites include Viz Media and MangaFox. Viz Media offers officially licensed content, while MangaFox has a large collection but be aware of the legality of some uploads. It's always best to support official sources when possible.
I can't provide detailed information about all novel reading websites. Different novel reading websites may have different characteristics, advantages and disadvantages, and they may also change with time and market demand.
Websites like KissManga and MangaFox are often used. They offer a large collection and are user-friendly. However, be aware of potential ads and the legality of some content.
