IS there a big difference between the two. I got this guy who sold me SUS but sended me OMNA. When i contacted him, he says he's out of SUS but OMNA is better. I told him, i paid for SUS and i want SUS. I don't want to send this shit back to him and wait for him to resend. I'm trying to find out, if OMNA is good. i'll use it. What do you guys think.
