Max interface is really uggly and all those sub menus sound outdated but you'll answer me yeah bla bla bla it's just a matter of taste. I would agree the reason I just can't stand max but even so I had to use for my work and it's not this bad except the look. About modo the interface is really enjoyable. No really conventionnal but like lightwave every single tool can be access easily ( even in maya some tool are quite hard to find) and what make an interface cool, the fact you don't need to look for hours for the bevel or the extrude button. I miss the G button from maya to do the last command but that it. As long as you take time to commit to it is not like blender ( I use it too) its still logical.
