I can only share my experience on the Megalight. You can absolutely not go wrong with this board. If powder is your thing like me you'd be hard pressed to find anything that matches it. Yet on groomers it absolutely flies with amazing stability at speed. The edges are what I'd describe as serrated, they are equally spaced high and low points similar to race skis.
The reviews online are spot on from my experience. If you can find one rest assured you will be more than satisfied.
Hope that helps an good luck.
