Minus genjutsu Hebi Sasuke would have had a tough fight against full power Orochimaru or possibly lost.
Once Orochimaru would have used Edo tensei Sasuke would have no chance of winning.
He only managed to kill Oro because of genjutsu and because at that time Oro had no arms to cast handseals for powerful jutsus like the edo tensei...
