Things I like about this set:

1.  Simple, attractive design.
2.  Sturdy construction.
3.  High edges on the plates prevent food from sliding/moving where it shouldn't.
4.  Absorbs minimal energy in the microwave, so the food gets hot while the plates don't (for two minutes of cook-time anyway).

I really have no negative observations.  Metal silverware leaves marks, but those are expected and can be removed.
