In a trending market I still firmly believe a Swing trader will beat most day traders. However it is looking to me like a really good daytrader can do very (trading the right markets) regardless of the market type given the added leverage available intraday... The added leverage used properly can more than overcome the occasional swing trader benefit.. the opening gap.
Even when I was "Swing Trading" I always had a tendency to daytrade so I am predisposed to it... Ultimately a hybrid probably works best as each method helps the other... Oddly, intraday charts look a lot like Dailies with the same setups except the gap risk is eliminated..
