I haven't. The SMD2727 is pretty good. I personally still like the 3535 the best for brightness. The Gloshine was using some SMD's I was unfamiliar with.
Wish there was a good tool to compare the different SMD chips in regards to the color spectrum and the intensity for each color. There's a very dated version floating around on wiki but it doesn't even have the 2727 on that list.
