Should I use Milotic, Slowbro or Rotom?

I’m running a sand team with the classic trio of Garchomp, Excadrill and Tyranitar/Hippowdon. The other three are a fire, water and grass core. But I’m having trouble who to pick among the three as my bulky water type

Milotic has been the best bulky water for me for as long as I played Pokemon but flame orb + sandstorm is gonna hurt a lot considering this is gen 6. Rotom and Slowbro also have very cool abilities that make them useful but they can become set up fodder while Milotic has dragon tail for it.

So what are the complete pros and cons of each of them when compared to each other?

I would recomend Slowbro out of the 3. As you say, Milotic will get worn doen by Sandstorm + Flame orb. Rotom-Wash has the problem of having a statline of having to either be fully offensive or fully defensive and sacrifice the other, which will add to your concern about pasivity.

Slowbro though, takes the Sandstorm damage easy thanks to Regenerator, and thanks to Calm Mind, isn’t passive. Try running a set like
