I have a few try and double squares. I have to say for my money I prefer a regular engineer's square. The Groz's I have seem to be plenty accurate for me (at least they're all as inaccurate as each other ). I reach for the double square when I have to make a shallow registration or if I need to use it as a scribing gauge or to measure with.
But there's something about the lack of a knob or any markings on the eng squares that makes me love them when simply striking square.
