TL;DR: Samsung is better, according to the author.
Some questions remain though, as Google’s Magic Eraser gives multiple options for object removal. Some are quite bad or blotchy, others are nearly seamless. Don’t like any of the options it’s provided, then ask it to try again. The author doesn’t touch on this at all. Did they select the first option everytime? Was this the best of the options they were provided?
Appreciate the reasoned response. It was my thought in reading the article as well too.
