I used a Hitachi that I borrowed from a neighbor before buying this one. It has a little more weight, so it makes it a little bulkier. Toggling triggers to change actuation type is an utter pain, and it's difficult to reset in single fire mode. So pulling the trigger will fire the nail unless you physically pull the trigger before placing the tip. The only other downside to this nailer is the push button depth adjustment, it really doesn't do anything for small nails. Once you get used to how it works, it runs smoothly and drives the nails well.
