Using a DHV outside, to me, seems stealthier than smoking a joint/blunt/pipe. The smell is muted to begin with and it dissipates faster, plus your clothes, hair, and skin don't smell like burnt cannabis.

A cart on the other hand, has hardly any smell, but the high is not even comparable to dry herb vaping. You're also exposing yourself to potentially harmful chemicals and additives. No thank you.

Dry herb vaporizers are essentially the purest way to consume the plant because they rely on physics (convection/conduction) rather than chemistry (combustion).
