They're both the same. The one on the top has cartridges. You can tell because they little plastic "condoms" are flat on one side and there is only one per cartridge. Those cartridges are pretty useless. You're going to want cartomizers instead. You should get whichever version is the best deal, including at least 5 cartomizers. Then, its a good idea to get 5 more. 2.0-2.5 ohm Boges are what you want.
