For flower, I only have the Herbal Aire. It's a desktop, light, not gonna break if it gets knocked off, great flavor, adjustable temps for different flavors, flower crucible can be packed as loose or tight as you want, no need to grind bud.
A nice even draw that;s smooth. Ya can make yourself cough, but ya have to TRY to do it.
Clean up of the crucible takes seconds between loads and I've yet to put that in alcohol to clean. It just doesn't need it. The plastic. part that holds the crusible, feels and looks kinda like Teflon, has a screen that get dirty from the vapor. It gets brushed off when it needs it and cleanied in iso when it nedds it.
It has crucibles with glass beads that you can use concentrates with, but it just doesn't seem to be it's strong point to me.
Not one problem in a year with almost daily use.
For Hash, it's the Yocan Evolve Plus portable. It's cheap, simple and gets the job done. It's not fancy. You control the temp by how long ya hold the button. You can choke the hell outta yourself if you want to do so, but it's easy not to do so. Great battery life, easily fit in any pocket and you can store concentrates in the silicone lined compartment on the end. You can leave home and stay lit all day and then some. I've had better luck with the stock coils that come with it. Depending on the quality of your hash, a quick puff from your mouth will clean the coil enough to reload Just soak the coil in iso over night when it needs it. It will hit hard or as soft as you want.
