We tested them out all last turkey season. Good blinds, very comparable to Double Bull, but they are smaller as well. I wouldn't say the windows are better, just different. Great blinds though, I LOVE the leather reinforced corners for the rods. I think the fabric is just as high quality as the DB which I never thought would be matched either. I am comparing it to the DB Matrix 360 though.
Both are great options, I would buy the rhino before the matrix IF I was paying full retail for either, but deals are always around to be had. I got my Matrix for MUCH less than retail for the Rhino, so all is relative.
