I understand the arguments for Water when looking specifically at the concept of checking top threats. I just have a hard time seeing ANOTHER Water pokemon in OU. There are so many other great Water pokemon, one of the only ways we can successfully get this in use would be to outclass many others. If we outclass many other Waters, we'll have to make this thing spectacularly powerful and versatile. If we go with Water, this pokemon will be competing for a team slot against stuff like Gyarados, Swampert, Starmie, Tentacruel, Vaporeon, Kingdra, and Suicune. Obviously teams can and will carry more than one water pokemon -- but there are lots of good options when it comes to water pokemon. OU waters have a lot of variety and can do lots of things. If we make a water pokemon, it will be very hard to make one that fits on a team better than the waters already available. I'm worried that the way we make it "fit", will be by making it "better". I hope not, but it does concern me. I'm voting for Ground, because I think the field is a little more open for us to make a pokemon that can fit on a team. Pokemon like Fidgit, Swampert, Mamoswine, Gliscor, and Hippowdon are the primary OU Grounds. Those pokemon don't have nearly as much role-variety as the murderers row of water pokemon I listed earlier. There is still a lot left to be done with Ground.
