Yes, cartomizers are generally aluminum narrow cylinders that include an atomizer (coil) surrounded by some sort of absorbent mesh that acts as a wick. These can be used stand alone or inserted into a tank. When inserting in a tank you punch holes on the sides of the metal cylinder to allow
juice to seep from the tank into the tube and be wicked up by the mesh. The clearomizers do not have this mesh, but have distinct wicks instead. The word "tank" can be confusing because it is used to refer to both cartos and clearos, to describe larger capacity devices. The Stardust is a clearomizer, while the Vivi Nova is a clearomizer tank. The mini Vivi is something in between. The T3 looks in shape like a Stardust but has much larger capacity so it further blurs the terms. The Boge (sp?) is a cartomizer which can be punched and inserted into a cartomizer tank. A cartomizer and its tank are two independent units, while a clearomizer tank is one integrated unit.
BTW, the Stardust comes in two forms. The sealed Stardust is the one you've tried and I had the same experience, too much leaking and hard to clean. But it also comes as the Stardust Replaceable, which can be taken apart and the heads cleaned, dry burned, and replaced, like the mini Vivi Nova. The Stardust Replaceable works much better than the sealed Stardust in my experience.
You may want to try the bigger Vivi Nova. It uses the same heads as the mini Vivi but it is easier to refill, the mini Vivi being a little tight at the opening. I am just trying the mini Vivi for the first time and the bigger Vivi may just vape a little better. Too early for me to reach conclusions yet.
Edit: After
vaping a fill and a half on the mini I would say it is as good as the bigger Vivi Nova, which makes sense as they use the same head.
Wait so I am getting these terminologies wrong huh. So the visions like the stardust and mini nova are clearomizer tanks not cartos?
I am very satisfied with the mini nova. I am reall curious to see what everyone prefers. I've used the vision stardust and I loved it because of it's great vapor production and flavor but it leaked and couldn't be cleaned so I switched to the mini nova and I love it (it's only downfall IMO is it seems to mute the flavors a bit). I am curious to try other versions but I'm hesitant as I really like the performance of the mini nova so far. It's very reliable and doesn't leak at all.
