Yes, as mentioned, the CE5 / Stardust is visually identical to the CE4, but has replaceable heads. If you go with that style, get the heads from the same place you get the clearo. While many will work with other "brands", some don't, and it's a real pain to get a box of new heads that don't fit!
Also true, bottom coils (Evod, T3, Protank are examples) seem to do better with higher VG, but in my experience, top coils (CE5, Vivi Nova, etc) don't seem to gunk up as fast if you vape a dark or sweet juice.
So I have both (along with other devices), and fill to suit.
