Bogo microfiber ?

I wish I had the answer to this as well. I assumed that the 600 was better because it is a heavier weight but I made a post about it and people really liked the supreme alot as well. Either way better get it soon bogo is going to change sometime today. Here is the post I made about it:http://www.autogeekonline.net/forum/auto-detailing-101/49713-deluxe-jr-600-microfiber-towels.html

I ended up getting one of both!

I just ordered on of each on BOGO cause I don't know the difference.

No, they are both very nice and similar. Get some of each just for variety. Can't go wrong either way
