Stupid, if only making applications only for Linux?
If you want to distribute applications only for linux, appimage can be the best choice. Because there is no need to pay attention to the very complicated dependencies in Linux.
But if you want to distribute your multiplatform application, Installbuilder is recommended. If your application opensource, you can get a free installbuilder license for all platforms.
Example blender Installer
VMware InstallBuilder on BEE free OS
