I agree in general but I don't think the choice is quite so binary -- power or ease of use. To use Poser'd magnet tool as an example. Yes, you can do a lot with it but it is hardly intuitive or easy for many people to use. ZBrush and Amorphium take the same task and use a sculpting metaphor that is easier to grasp. Some variation on the grouping tool where you could color the areas of the mesh to be affected, using different colors to define the strength and perhaps something other than the clumsy (IMO) three piece magnet would make things much easier. Too often, the problem with software isn't a lack of power but rather a lot of power locked behind an inscrutable interface. The Macintosh was a hit, not so much because it could do anything that other machines of the day couldn't but because it made doing it easier for many people.
