I have ordered several juices from several vendors, and Nhaler's
juice is my favorite. I am not sure what you mean by cleanest, but the flavor is fantastic and the juice's vape beautifully. I just placed an order with VV because I wanted to try VG juice but I have not gotten yet so I can't give an opinion. Overall though, I have a hard time believing it will outdo Drew's (Nhaler owner) juice. I love everything I have ever bought from him. He also sells samples (as does Vermont Vapor) if you want to try out some before committing to the big bottles.
