I use Scribblehub much more than Webnovel, but I sadly think I have to go with Webnovel. I've read too many novels on Scribblehub that get dropped, so I kinda have trouble convincing myself into reading novels that are out of my comfort zone, since even if I like it, there's a very real possibility that it will either get dropped, have months long hiatuses with no warning or explanation, or they move to a different site. I don't have these concerns with Webnovel, and as such I check out more new novels there than I do on Scribblehub. Sure, the content there is FAR more generic, but I'd rather suffer from too much regular content than get invested in a unique novel and have it ripped away from me with no explanation.
That said, Not voting for Webnovel since the few novels I've read that are truly Scribblehub exclusive and haven't been dropped, moved to another site or had the author mysteriously vanish are AMAZING. I just have a problem getting into novels on Scribblehub, but the few that I can get into are worth it.
