For anything that is primarily made of flat surfaces or simple geometry, FreeCAD's realthunder edition is far easier to use, because the interface is based on 2D sketches and requires a lot less thinking and interacting in 3D, and you don't do a lot of precision mouse work dragging things into place, just approximations you constrain with numbers.

Although that might actually be a negative, because it doesn't teach you the methods you'll need for more organic shapes.
