I totally agree with you, Carly! I'm in awe of Duff's cakes, too. But you can't beat classic buttercream for flavor.
I guess it's kind of like digital photography vs. 35mm SLR or large format classic film photography. I can get great results with digital -- and can fix in Photoshop whatever I can't get with the camera. But it takes a lot more artistry and skill for me to get great results with my Canon AE-1 -- and I get more satisfaction with that.
