Aside from the fact that is is proprietary and cloud based, I love OnShape. It does have some limitations, like operations that logically should make sense but will just fail, but this is what makes CAD very hard even for a large experienced team like OnShape. But I like that I can run it in Linux because it is browser based, tho I would prefer a local native app. Onshape is hard to use on a slow connection. But I use it to design all kinds of complex robots and it is great.
