Welcome to ECF and congratulations on your decision to begin vaping!
If I were you, I'd look for a juice that has a higher PG ratio. That will give you more flavor, but these juices are more difficult to find because of the sub-ohm vaping trend. Quality juice makers that offer more PG include:
Ahlusion
Custom
Heather's Heavenly Vapes
Heather’s Heavenly Vapes, Top Quality Custom E-Liquids
Quick Nic
Quick Nic Juice
Cloud Ride's Classic Collection

Halo -- All except their max VG juices

There are other vaping devices that will deliver better flavor, but if I were you, I'd look at upping the PG content in the juices you are using. You can switch your e cigarettes later, if you want to. Right now, just find a juice that works for you and is satisfying.
If you are having a hard time with vaping and are still craving analog cigarettes badly, I recommend you increase the nicotine content in your juice until your cravings are reduced. I don't know what level of nicotine will be enough for you, but I started vaping 12 mg. nicotine on a device that is very similar to the one you are using, and it was not enough for me. I had to find juices that were 18 mg. nicotine to be able to lay down the analog cigarettes and vape exclusively. As a point of reference for you, the amount of nicotine needed by each person is usually related to how many analog cigarettes per day you used to smoke. Before I began vaping I smoked 1 - 1 1/2 packs of analog cigarettes per day and 12 mg. nicotine juices did not provide enough nicotine for me to stop vaping. Once I increased my nicotine to 18 mg. I could lay the analog cigarettes down permanently with no looking back or longing for an analog.
