Not as good as Cura but, probably 2nd best.

Btw I am linking to your list on my Linux software index TuxHub.net 👍

Thanks for the suggestion. I will add slic3r to the list when I have the time (or better yet you can help me by opening a pull request)

Please note that the list is not about the best tool or comparision between tools. It is more about safe-to-use, reliable and maintained software that runs on linux
