It honestly depends on the location of your property within a proposed unit. If you are in the middle of a proposed unit without any laterals near your property line, going with a non operator may or may not give you better lease terms as you would be working directly with them and then they in turn would be a non working interest in the wells that are drilled. They take on the responsibility, risk, and costs to drill their portion of the well!
However, if your property is near a unit boundary or worse, up against or boarding another units end point, not going with the operator could put you in a position where the operator could exclude you from a unit. This could reduce the likelihood that you’d ever get drilled because of a lack of space between your property and the two units you are sandwiched between. This would pose a major risk that is location and situation specific.
