Welcome Aboard
Great start to your quitting smoking coming here. You will be overloaded with information, the thing I always think best to start off with is something you'll use. Try the look and feel of them, see how they draw nothing worse that getting something you won't use.
We have a saying here 'KISS' Keep It Simple Stupid, that's a good place to start. A pod system, an AIO (all in one) or a basic stick. My preference at the start were products by Innokin and Aspire, again not a bad place to start. I still use products from them now The Tigon and AVP from Aspire and the Adept from Innokin are in almost Daily use. All fairly new products so actually thinking about it I still buy products from them today!
Good Luck kicking the awful habit, you can do it, if I can do it, anyone can.
