At the sale price, I think it's a pretty good deal. IMO, it's main pro is also the reason for its main con. It's a very soft waffle weave, but because of this the towel is very prone to snagging. On it's first use, one of the Sonus Ultimate Drying towel I purchased got snagged slightly. Normally that's no big deal since other towels I have snag or get caught also.
But after I had washed it, it appeared that somehow the hot water during the wash caused that snag to singe (think of taking a flame to a thin piece of plastic, but in this case it was a piece of fiber/thread). It left about a 1 1/2" line that unfortunately was hard enough to mar paint.
The good thing though was that Autopia's customer service was excellent and Lynn shipped one out promptly, even though it had been a couple of months since I ordered the item.
The other towels I've used since then (same kind) has never had the same thing occur (they have some little snags here and there too), so maybe it was just a bad towel. If I had to pick one for durability, I would say that the Der Wunder drying towel will last longer, but at the same time it's not as soft. I really can't say that one towel is better than another. Ultimately, it would come down to price.
