Skarm, Swampert, and I believe Bronzong or Gliscor are all fairly reliable Stealth Rock users.
The moves is either extremely good or not that useful, compared to spikes, depending on the opponent's team - but with the advent of so many pokemon that have Levitate, and the fact that it hits Salamence and Gyarados (as well as Infernape) hard, there's a good chance it's better than Spikes in this gen, due to it only taking a turn to set up at max power.
Still, it suffers in that it only does 6.25% to Steel-types, and the fact that Ground types, fairly common this gen as well, also resist it.
However, there is the fact that Rapid Spin, as far as I've seen, is uncommon. If you're worried about the Fliers in this generation, notably, as said, Gyara and Salamence, I'd definitely put someone with it on the team.
My thoughts.
