Blender is an abomination. I uninstalled it year ago and swore to never use it again (for mental health reasons). I'm hobbyist 3d modeler, I can afford not to have blender installed. I use mm3d daily and occasionally wings3d. Both are in Ubuntu repo. Using blender made me angry, even starting blender made me angry. Using mm3d makes me happy, it would be nice if it had more features and supported more formats but it's good enough for what I do.
