No experience with the Air, but my Airizer Solo 2 is my most reliable vape by a wide margin. Going for many years now, just as good as new. No removable batteries though. My understanding is that the 3 is great as well.
Other premium options might be the TinyMight 2 or one of the Storz & Bickels. Maybe even dynavaps and a heater if you're mostly vaping at home, that's really my daily driver.
