Which subscription would you recommend more Netflix abo or Anime on Demand Although I bought a three-month anime on demand abo 2 weeks ago, but?

After that, I'm thinking about going back to Netflix because there are lots of Anime on Demand TV shows on Netflix

There's nothing wrong with switching back to Netflix or having both run in parallel. But I would first look at the corresponding titles on AoD and then switch to Netflix. If you get the titles in a month, you can use the trial month and pay nothing for that (if you cancel in time).

If you only or mainly like to watch anime, then I would advise you Anime On Demand, otherwise Netflix would be more advantageous.
