Everyone is different, so what’s best for me or anyone else may not be best for you. Having said that, some general advice-

My suggestion will always be dry herb vapes. In my experience they offer the best highs and the best flavor, with the added benefit of not inhaling the nonsense in 510 carts or smoke. 510 vapes shine for their discretion and ease of use but fall flat on flavor and smoothness imo.

In general the more expensive devices get you better performance or features, but there are options that punch above their price point or offer better value than others. My advice would be to check out what features the top offerings have and look for entry level options with similar features to try out before you sink a lot of money into it, unless you aren’t worried about the money.

Are you wanting something portable or something to stay home and plugged in?

I love Arizer and have reliably used the same ones daily for years. The Air is slightly smaller and has replaceable 26650 batteries whereas a Solo II has an internal rechargeable battery and is slightly bigger. Both are portable but probably a little clunky to carry around in a pocket. They probably will be on sale shortly with 4/20 approaching.

Edit: dry herb vapes make your herb stash stretch an incredibly long time versus combustion because it uses so little.

Go for a Volcano if you can afford it.
