First problem, that URL link goes to a dead website for me, which is a major issue given the name of Paint.Net is it’s URL…

But yeah I mean sure Paint.Net is good in terms of functionality!

I wouldn’t recommend it over Gimp though, sure Gimp is annoying but Paint.Net is a shovel where as Gimp is a fully featured construction crew with excavators and equipment. Different uses and design goals but the important bit is you can easily ask a construction crew to dig a random hole for you whereas it is much harder to ask a shovel to clear a building site and dig out a pit for a foundation for you… so I tend to recommend familiarizing yourself with Gimp and just skip Paint.Net unless you have a specific need where it fits better.

Learn Gimp once and use it the rest of your life, shrugs it is the nature of successful Open Source projects like this that after they reach a critical mass of functionality from two decades of development or so there just isn’t a great reason to go with anything else in my opinion (unless you want to drop money on a paid image editor from a company less shitty than Adobe).

Gimp will be around, being developed and used all over the world long after you are dead. Paint.Net mightttt be if it continues to grow.
