Cons
Con The web site's domain is no longer available
Using the WayBackMachine to get the site's contact email address, I attempted to contact the developer to find out what the story is. There has been no response. The WayBackMachine's last archive date for the site was 11Jan2016. Their cached version of the paint3D.net's forum does not have any post explaining what happened.
Con Not a voxel program
This is a paid texture program. Why is it in this list?
Con Voxel sculpting hits your system
Voxel is quite heavy on your computer, if you intent to use this as your main model and sculpt app do enough research to see if your computer can handle it and if you have the right graphic card for it. If you really have doubts , just go ask in the forums.
Con 7 layer restriction in the affordable version
The cheapest version available only lets you paint on 7 layers, which is very unfortunate.
