I'm left handed but I've always used right handed scissors in my right hand. I can actually cut with either, but cutting right handed has always been more natural for me. Using the left handed scissors in my left hand requires more concentration.
The only real benefit I've ever noticed of left handed scissors is that when you hold them in your left hand, you can see the point on the paper where the blades are going to cut. Holding a pair of right handed scissors in your left hand (or vice-versa) obscures that point behind the top blade, making it a lot harder to make accurate cuts.
If you try holding a pair of regular right handed scissor in your left hand you should be able to see the issue of the top blade covering the part of the paper you want to cut. Which let me tell you, makes following dotted lines a lot harder in school if you're using them on the wrong hand...
That's the only difference I've ever come across anyway, not sure what other commenters are talking about with the paper turning sideways!
