The isn't any right answer to this question because everyone has a different opinion. Many, many vapers love tanks with cartos in them like boges. I hate them. I taste the filler, I get dry hits no matter how much liquid I put in or how I fill it, and while I am glad they make so many people happy, they just don't work for me.
I'm a clearo girl. I love Stardusts and vivi novas. I do drip onto an atty to try new flavors sometimes, but 98% of my vaping is in a clearo of some kind. I think they give great, clean flavor and good vapor. But there are vapers who hate Stardusts as much as I hate cartos. It's just up to the individual. You should probably try both to see which gives you the best experience.
In the picture you sent, the one on the left is your atty. If you insert that into the holder, put the cone on, and then add a drip tip instead of the plastic tank that came with the ego, you can drip juice directly onto the atty and vape. It gives great flavor, but you have to drip a couple of more drops when it starts to lose flavor (after five or six vapes). There are other attys that are better for dripping, like bridge less ones.
