If you just don't like the interface then whatever, but it is quite erroneous to describe Wings3D as "amateurish" or "basic." Wings is a very powerful modeling tool, incorporating the latest subdivision surfaces technology, and is a favorite modeling tool in the 3D art community, including many professionals. Milkshape on the other hand is barely adequate for the modeling needs of game development hobbyists.
Milkshape is very simple, even primitive, but that's what I like about it. It's not the ability to move vertices around; it's the fact that you HAVE to place all your vertices that I like. If, for example, I want to limit a model to 200 polys (because there may be 100 of them on the screen at once), Milkshape gives me the ability to toss something together from scratch without having to think too hard about LoD. Add in some tricks of the trade and you can make pretty detailed models with very few polys.
Wings3D is great too, but it's a modeler with a different purpose. I have it and use it when poly count isn't that important. For that matter, Art of Illusion is another cool modeler with booleans, so I use THAT when I need booleans. :)
