The way I see it you potentially waste juice with either method. With dripping you will occasionally flood, with carts you will waste what is left over in an old cart when you finally throw it away. There's obviously more to it than that, but all I'm getting at is as people are saying find what works best for you. I like to drip about 70% of the time. But I still use carts when dripping is less than convenient (mostly when driving, though I've been dripping and driving lately too). There are also some cart mods that users swear by, just keep trying till you find the right solution for you.
