All the higher priced brands are better at building and give better life in my experience, and they look better generally. They do have better UV protection coat per coat compared to cheaper brands. But I can't settle on one of the top end brands, finding it that much above the rest, not yet anyway.

I just went through a quart of Flagship and found it similar to Epiphanes in thickness. It did build quickly. Next year, could be Letonk....
