Solid choices Uncle !
Frenchfry, what devices does the recipient of your gift use ? If it's a clearo with throwaway coils, you might want to stay away from want2vape which is the gunkiest of the bunch. MVJ is probably the cleanest burning from the above list, and the other two in the middle. My favorites are Goodejuice, N.E.T. and Mountain Oak Vapors. HHV is a good option for sweeter NETs and undoubtedly the cleanest burning of all NETs.
For synthetics, Indigo Vapers and Halo might be good options.
