Depends on how you like to do the weed. If you just smoke it, then go for quality. But if you make butter out of it, or tincture, then quantity can potentially be a better deal. For example, let's say you have the choice of an ounce of kickass bud for $300, and it's 21 percent THC. Or you could buy four ounces of schwaggish stuff, for the same price, and it's 8 percent THC. Well then, do the math: the schwag is a better deal, since you get more THC from the 4 ounces of schwagg than you do the one ounce of dank, which means more butter (for cookies/brownies/whatever) or tincture. Once it's reduced to butter or tincture, you can't really tell WHAT kind of weed it came from, so what matters is the amount of THC you get for your money.
