The strategy of swing or scalper are made for two class of people. some people are good at scalping and some at swing trading. There is nothing to compare between the strategies because we can not compare apple with orange although both are fruit. similarly it will be not wise to compare swing and scalping although both are trading strategy .

I think scalping is good and better and i am trading since a long time and i realize that scalping is better because i don't suffer a loss on it and earn some good amount of profit.
