I've been using this model Hitachi 15" miter saw since 1992, it's the best miter saw on the planet.  If you want deadly accuracy then this is the saw you want, why you ask.  Because the housing holding the swing arm in place holds it on both sides, not just one, no play whatsoever.  There's a little viewing window so you can see the location of the cut you're about to make, not some silly little laser that washes out so you don't know exactly where the cut will be.  The swing arm has and up and down adjustment so you can have the blade start practically at the vertical position.  The 15" blade cuts deeper than any other saw.  I've been in the furniture industry/wood working industry for over 40 years and I've seen every saw and type of saw there is, this one is the only miter saw I use, everything else can't hold a candle to this saw.  Waytogo Hitachi for engineering such a terrific saw!  The reason I'm purchasing another one is because my last saw came with the business I sold. This saw will be the 4th Hitachi 15" miter saw I've purchased, they're that good.
