sethkal...try all of it if funds will allow you too. Some folks like attys with a cartridge, some love cartomizers, some love to drip, and some love the ego-t system. You need to find the setup that works for YOU and only YOU. We can only give you suggestions which may/may not work for your situation. Personally, I use atomizers and drip to test flavors but I'm a cartomizer cat at heart. That doesn't mean you'll like them but if you can afford to get some, get Boge 2ohm for the ego batteries. Cartomizers are nice for when you aren't going to be where or in a situation that would be appropriate to drip in...like driving or work. Leave dripping for when you are at home.
