Hi Mtn Mike,
I don't pretend to be an expert but I do know that the three layer waterproof/breathable jackets are meant to be much lighter and more 'durable' - that is, they have extra rip guard. They're meant for hikers who go on more intense, high-elevation hikes. I wouldn't say that you made a mistake in buying them. Sounds like you wanted the best equipment and the 3-layers do tend to have a lot of extra features. But, if you're climbing in this area, I have to agree that I find these higher-tech jackets to be an extra, unneeded expense for me. They are lighter and more breathable - so it makes sense if you feel cooler in every season, even in the winter - or maybe, especially in the winter. I usually figure that if I'm hiking in the winter that I want a little more warmth on me and that usually means weight - I think in this case, the regular GoreTex (or its' equivalent) is probably a better buy for your money and will provide more warmth.
One material that I found is great in the winter is the PrimaLoft. It's made by a local company (Albany International) and was designed for the U.S. military for combat equipment. PrimaLoft is a synthetic down that is so lightweight and comfortable that you'll think you're wearing a spring jacket. It has an advantage over down though in that when it gets wet, it still insulates. Even around town, I've found I live in PrimaLoft throughout most of the winter.
My suggestion is if you're feeling a little uncomfortable with the better jacket, save it for the warmer wet hikes - you'll find its advantages then. In the meantime, check out campmor or some EMS clearance rack and get yourself a Gore-tex jacket for the winter.
You'll probably find people to disagree with me, but I think it's you that should feel comfortable with what you have and you should get what's right for you.
Hope this helps.
