We ended up going with these because we needed to purchase a lot of cushions, and the price was relatively affordable for a cushion with sunbrella fabric.  We love the fabric!  The cushion looks good and the ties work well.  My only complaint is that the cushion itself is VERY flimsy.  I only weigh 165lbs, but it still feels like these cushions squish down to almost nothing when I sit on it.  Our previous cushions were much firmer.
