Pros
Pro Free and Open Source
MtPaint is free to use and licensed under the GNU General Public License.
Pro Seems stable and light
This is an expectation though, since was not used/ tested long term.
Pro Simple to use, initiative
Pro Full set of image manipulation tools
Pro Cross platform
Cons
Con Is paint
Same use As Win98 Paint
Con Snap only
For Linux, the choice seems to have been to offer PencilSheep as snap only, sorry, no .deb, no .rpm, no nothing. If you do not have/ use snap (for many, including valid reasons), PencilSheep is beyond your reach.
Con Project no longer supported?
Although it is offered widely (including Google), the devs website seems dead. Hence, it is unclear whether it is still developed and supported actively.
