I've tried all of these for an extended period. 
Cigarettes are awful, if you've smoked for over a year switch to any other tobacco product for a week and be amazed how often you were needing to take a break just to catch your breath doing basic stuff.

Vape, it's the gayest tobacco product, nothing like telling a grown man you need something strawberry milkshake flavoured to help with your addiction withdrawals.

Nicotine packets are literally worthless, they might help some people but they taste like nothing take forever to kick in and even at the higher doses your not always sure if they even worked or not.

Snus was great and had some crazy dreams if I fell asleep with one in my mouth. Some of the "traditional" flavors tasted like cancer and burnt asshole, but the mint or fruit flavors were pretty great. Had to go back to vaping after my gums receded and turned purple.

I *really* don't think you're supposed to be sleeping with snus in your mouth.
