Pax 2 is a reliable choice for dry herb, no need to spend the extra $100 on a Pax 3 if you don't use oils or shatter. Small and sleek, easy to vape on the go but also a great choice for a low-maintenance home use.
Note, if you really love a smooth portable experience, I'd recommend trying the volcano's portable. It's incredibly powerful and smooth due to a much longer vape chamber but is significantly larger and more expensive than the Pax.
If you're going to get a stationary vape, always go for the volcano. The volcano hybrid can manage dry herb and suspensions afaik, but their original and digital versions also slap.
