I wasn't passing any judgement as to whether it's good or bad to use just a subset, it was more a comment on how well that subset actually works.

My point is that a simple program like Wings is entirely focussed on a limited number of tools, but they work really well at what they have to do. Those same tools would be just one subset of tools in a big application and as such they might not be quite as good at those same tasks, they don't need to be if there are other ways to skin the cat with other toolsets or more sophisticated (but less-used) tools.

For example I don't think the selection tools in Rhino (selecting edges, verts, faces, converting selections from verts to faces, growing/shrinking selections etc) are anywhere near as good as the selection tools in Wings. But I wouldn't expect them to be because messing about with that stuff is central to Wings (a poly modeller) but a bit of a side-show to Rhino (a nurbs modeler which can handle poly modelling). I'm not knocking Rhino either, just suggesting that using any app for something that isn't its focus doesn't bring out the best in it.
