Sorry that's just your opinion.
When I see the following in your list:
- One App that was discontinued last December and is no longer available for download on Google Play.
- One App that hasn't been updated in over a year and has been replaced by a newer version with more capabilities.
- Apps that have limits on the size of the photo they can work with.
- Apps available on both Android and iOS that have limitations on the features for the Android version unless they have specific processors (while even the 5S with the A7 supports those features).
I know for a fact you just pulled those off a list you found somewhere. That and the fact you're comparing quick & dirty photo editors for the Instagram crowd with powerful tools like Affinity and Pixelmator.
