Haven't heard much bad, except from folks who drew tags and were placed on small ranches with few antelope. You should know what you are getting into, though, with a landowner tag.
I drew SE NM in 2007, with my son. We were assigned a ranch. We shot the only two bucks we saw on the ranch. As we drove toward Roswell, we saw a lot better antelope and far greater numbers.
As Oak said, depends upon the ranch. I know a few of the ranches down there and could tell you "Good or Bad," if it is one I am familiar with.
