I've played with both Drunken dragon 40+ and Hidden dragon 40+. I used DD on forehand and HD on backhand.
HD : non tacky / more bounce / heavier
DD : tacky / lighter /softer
For their price they are pretty good, but I'm currently not using them on my main blade. I switched from HD to something a couple of grams lighter and the DD tore into pieces after a couple of times reglueing it. I had glued it with an old thick batch of glue and the soft sponge couldnt handle it. Most people like HD over DD, because it's similar to european rubbers. Give it a try if you're looking for a cheap alternative to european rubbers.
