I have used the following blank cartos: V4L WOW, V4L CoolCart, Vapornine Turbo, generic kanger.
Of those, the turbo and coolcarts are the same. The WOW cartos are low resistance and therefor warmer vapor but must be kept wet to avoid running dry. The generics, just forget them. IMHO, they are only useful for testing new flavors or as a free sample from a vendor.
I have not used the premium carts from LiteCig but based on other posts here, the premiums are the same (or similar) to the CoolCart and Turbo. LiteCig also offers a low res premium which is probably close to the V4L WOW carto. Either of them should be good as long as you understand what each will give you. The LiteCig premium will give you a cooler vapor while the low res premium will give you a warmer vapor. The low res premium should be topped off frequently to make sure it is wet. If you plan to use 1 carto for a long period of time, like a full work day, you may want to go with one of the cooler cartos. (LiteCig Premium, VaporNine Turbo or V4L CoolCart) If you will be able to have a bottle of
juice with you and top off frequently, you may like the warmer cartos. (V4L WOW or LiteCig Low Res Premium)
To be honest, you will eventually want to try them all. Only after trying them will you know for sure which you prefer for yourself. I am currently in that phase myself.
Good luck!
