I like Below deck but i dont like nor watch any of the shows you listed. Below deck is,together with milion dollar listing,the only reality show that i watch. I dont think it is comparable to housewives so its hard to say. But in general i would say:if you like housewifes and shows like that you will like below deck,probably even more so then the other shows you listed. If you like below deck then that doesnt mean you will like housewifes.

Dont start with the "best" season. The seasons honestly dont differ that much in quality as some people here make it out to be.

1 sailing isnt way worse then 2 or 3. The bro crew season on OG isnt much worse then any of the other seasons (its actually one of the most entertaining seasons of OG). People here have their preferences but they seem to be mostly based on their favorit characters beeing in a season or not and how those characters are beeing portrayed.

You can start with any of the franchises but i would start with season 1 for sure. Og is rough and nasty. Drama and friction between the crew is the main ingredient. Med and sailing have a much more friendly atmosphere in general. If you are a us vieuwer then you will probably prefer OG. European vieuwers i think are more likely to prefer med or sailing.
