I've never used a LSV, but I think LSV and E-Nano are actually very similar and the biggest difference is the size. That LSD is very much like a bigger E-Nano.
They are both ata a core a ceramic heating rod a with a Wattage control dial. E-Nano has the rod inside a little steel tube, LSV inside a bigger glass tube.
They both have a straight glass vaporpath that can connect to water tools.
Both vapes are housed in a cylindrical insulating body, LSV has a metal body with holes, E-Nano a layered metal-wooden one.
So if you are deciding between these two, it seems like you have already decided what kind of vape you want and only need to decide on the size factor.
The LSV is much bigger with a bigger bowl, while the Nano is very small with a tiny bowl, great for quick and compact personal use and microdosing.
With the LSV you can vape huge vbowl, while with Nano you can only put very little in the bowl, vape it and then realize it's enough and save your herb.
