I certainly don't want to argue about which is better as I haven't played that one but Katana also has 155k puzzles! Users add a ton each day and you can follow your favorite artists. No purchase necessary and no ads (unless you watch one for some of the aforemented useless stuff)
I will say that there's plenty of garbage puzzles due to them being user-generated. And a good portion are color nonograms which I don't like all that much
