Yes, it's more about WU as some people say, still, 1/3 the WU from what I was mining in scrypt. My concern is that only conservative settings will be stable in vertminer, compared to more aggressive settings in cgminer for scrypt.
I think he means that you need to consider the price of the coin. I'd get ~$4/day with my 7850 hashing 365kh/s scrypt. I can get $6-7/day mining Vert at 160kh/s. Even if it went down to 120kh/s its still $5/day and better than normal scrypt.
