Intellicoat and Phototex are the two we use. We get GREAT image quality on our Roland with the Inellicoat. We get good image quality on Phototex, but I just think the colors pop more on the intellicoat.
If you are applying to a wall with any kind of sheen (satin, semi-gloss, gloss) the adhesive on the phototex is much stronger and will last longer. If the wall has a flat finish the intellicoat is a great product.
