If you are putting speakers behind it, make sure you test it.
The anchorage is definitely a nicer looking fabric, but in my experience it isn't as transparent as the 701 and it seemed to really clip my highs. I didn't love the burlap look of the 701 black sample, but I must say that once I had it on my panels themselves, it took on a much sleeker, nicer look. Now that my panels are in place they don't look like burlap any more.
If I were just doing panels with no speakers behind them, I'd go with anchorage. If using speakers, I'd go with 701 (Danzien may also work well--I actually preferred the 701, as the Danzian sample I received was a little shiny for me-- but it is all just personal preference).
