Are you looking for a home unit, something you can carry around?
Because herb and shatter are different ball games, you may want 2 different units.
For herbs the Silver Surfer is pretty good as a large tabletop unit, but you will tear through a lot of herb. Personally recommend the Arizer Solo 2 'cos it's economical, simple to use and relatively small to carry around.
For stealth the Pax 3 is pretty good and can be used with both concentrates and herbs.
I'm not the best person to ask about Shatter, but you may end up buying two vapes (and choosing your weapon according to what you want to put in it) as many of the 'Jack-of-all-trades' ones aren't that well reviewed.
