Ruger vs Scar Light - Competitive Play

I was curious about people's opinions about both guns in such a manner. The Ruger being considerably more powerful than the SL, just as light (afaik) with a slower reload and fire rate.

Are the two downsides of the Ruger compared to the SL enough to merit it being a suitable weapon for competitive play? Or would people ban it as well given the choice because of its damage?

Not entirely sure people's standing on the weapon so I wonder the thoughts on it.
