Hahaha, I've grown to love this question over the past few weeks. I'm a huge fan of Aseprite, and I don't have a bad word to say about it.
However, I could attempt to make the case for Stipple Effect over Aseprite a few ways.
In terms of what Stipple Effect can do better than Aseprite, or what it can do that Aseprite can't, I'd highlight some specific applications of the scripting system. If you are a game developer making a 2D pixel art game with a lot of animated assets of the same form (physical shape, dimensions, pose, etc.), Stipple Effect can really expedite the art process.
Imagine you are making a game with tons of NPCs, each of which has to have idle animations, walking animations, and a certain number of action animations. Or a game with significant character customization in the form of clothing and vanity items. At present, you would probably have to individually animate every NPC and every clothing item for each animation. Using Stipple Effect, however, you can spend a bit of time configuring a lookup relationship between a single texture and an animated UV lookup asset, and map the texture to the animation via a preview script. In the long run, this will save hundreds of hours of tedious work, as you will only have to draw a single texture for each item/NPC you are adding to your game.
Besides that, Stipple Effect is much younger than Aseprite. David has been working on Aseprite for over 20 years as far as I know, while I have been working on Stipple Effect for just over eight months. The program is improving at a much more rapid rate, and will likely receive more substantive updates more often than Aseprite will.
Stipple Effect is only a quarter of the price of Aseprite presently to reflect that it is still a nascent program with less polish, so there is an economic incentive as well.
In summary, I would say you should decide whether Stipple Effect is the best fit for your individual needs, and whether you're willing to take a chance on less proven software with a huge potential upside.
