I used to only drip but now I use cartos or tanks 95% of the time. I am dripping right now since I got a sample bottle of Dulce de Leche from BMV and it's not really enough for a carto. I've also got some high VG liquids that don't work well with cartos/tanks so I drip them. I just finished cleaning my tanks yesterday so I'll probably get them loaded up tomorrow. When it comes to the cartos for tanks, putting the holes in them only takes a couple of minutes (I slot them with a Dremel). I like going a couple of days without having to refill at all.
If dripping works for you, stick with it. What works for one person doesn't always work for another.
