My family both won Green Card Lottery which and then got a refugee status. I am pretty sure that double thing is quite rare. Anyhow, either of those programs provide far more support than h1-b or spousal visa, like both allow right to work right away, the refugee had some help with health and income benefits during your first year. I also have known quite a few couples with an "imported" wife, and at least one with an "imported" husband. So yeah, ranking of the programs is refugee->green card lottery->spouse->h1-b with student on the side.
