I would agree with Roy....it varies from kit to kit....as someone who only does US subjects, Eduard is fine, Griffon is good and some of the new arrivials like MK are ok.
In general, if you are building a more recent kit, you will be left with about half the PE unused when you are done. Many of the items they give you just don't need to be replaced.
I have yet to build a model with PE and use the whole PE set. With that in mind, look at price. Eduard gives you details and is reasonable.
Some of the expensive Griffon and Aber sets can be a disappointment as to how much you spent and how much you use!!
