what is the difference between vodka and straight alcohol

[Rod]

I use a basic sugar wash to distill my spirit and get something reasonable , about 86 to 90 % from a reflux still

I use the spirit to make gin , fruit macerations ( alla panty dropper ) , sambuca , lemoncello etc

and have used commercial essences

I have made tequila using blue agave concentrate ,

rum from molasses

brandy from wine

I was thinking of making some vodka , which I do not drink , but have mixed with other stuff for the boss , screw drivers etc

what advantages would I get from making vodka over using the alcohol from the sugar washes
