I’ve only made GIFs in the past, so there’s a bit of a bias. Plus, it’s easier to make them and view them since they are the de facto file type for animated images.

I never heard of MNG. :v

APNG is nice. No color restrictions and better handling of transparency. It’s a high quality PNG, but animated! But since I use Chrome, that means I must use an extension to see it.

So yeah I guess that I like APNG better when it comes to the image’s quality.
