Looking for Opinions on non-filler carto's

[rel322]

I'm looking to moving away from non-filler carto's because of the problems that I'm having with them.
I'm not sure how many different kinds of non-filler carto's there are but i know of G4, G5, and CE2.
Are there any others, and which is the best? (in your opinion, easiest to fill, clean, etc.)

If you're using ego type batteries there's also the tanks (ego-t, ego-c, etc.).

Honestly, I haven't had much luck with those you mentioned. However, the stardust is pretty much a sure thing..it works very well and is easy to fill. It's available from a few different vendors who call them slightly different things.
