I used the hitachi quite a bit today and I must say this thing is impressive. It makes the dewalt feel like a toy. It sinks nails and, unlike the dewalt, it doesn't cry like a little ***** every time you pull the trigger. It shoots the nail, it shoots it fast and it shoots it deep. Every time. It doesn't know the difference between a double lvl and a 2x4. Nail goes in deep.How it holds up doesn't really matter to me because the thing has a lifetime warranty.
