It would depend how good the reg weed was. Personally, i'd buy the quality gram and get some kief out of it so it would be worth it for me. $20 doesn't mean that much to me. But, my advice for you is go for the reg weed coz it'll last longer if you're smoking bowls or joints. I never buy just a gram or two though, minimum 8th but usually minimum 1/4 these days lol.
