I really like Texasbbqrub.
I've tried all three and have decided that I like the original best as it's versatile and suits my tastes on just about everything.
I would like to say that when the stuff first got here and I smelled it through the bag it took me a while before I used it. I just didn't think THAT smell would translate into something I like on the smoker or grill. I was WRONG.
My personal opinion is TexasBBQrub is the absolute BEST on the grill. The rub's makeup just makes a really great flavor over higher heat and fantastic caramelization.
As was mentioned before, make sure to use worcestershire sauce on the meat before applying the rub or I mix worcestershire powder into the rub. There's some sort of magic that happens with this combo. The rub is MADE with worcestershire in mind.
Have fun!
