When I first begin posting I started with Tapas. the audience grew slowly and I was anticipating and wanted it to grow more. I also had recently created a Patreon account which wasn't getting much traffic, however, the moment I started posting on Webtoon, my stats shoot up and I was getting a lot more active readers there than I did in Tapas. a year and a half have passed now and I see a steady flow in traffic. Tapas has 3.1K and webtoon has 3.2k even though at some point webtoon was much higher than Tapas.
Overall, I like both. different audience, different interaction. but my best advice to you is posting on both platforms. webtoon grew my patreon just a bit. any advertising is better than no advertising. so i prefer both. matter of fact, I'm looking to find elsewhere i can post so i can have that exposure.
