I have an oes standard and just sold my superfly. Both were high quality tarps. I really love my standard and the high quality. Brian really goes above and beyond to make a tarp that will last. My experience with him was great, he made mine custom in black which is important to me to have choices.
I had the olive brown superfly, I believe it is the one that was outsourced to china but the quality was still great. The color is nice, in some light its more of a brown and in other its more of a dark olive green. The biggest difference is that the cat cut are less deep on warbonnets tarps. So it may take a steeper pitch to getthe OES doors completely shut.
Like I said before I like to choose the color and features. If I had had to get another winter tarp I'd go with Brian for that reason but the superfly has everything you need. Wilderness logics will also make you one slightly custom.
