Sorry I can't compare it to the Just Cuz, but I believe it is a little more comfortable than my TruBall Ultra, because the corners are rounded nicely. My "large" is about the same size as the Atrraction large. Also it shortens my draw length slightly from the TruBall, because the jaw is closer to the handle.
For me, the different cresents make less difference than the position of the cresent as far as how fast it releases. I like it, but Scott, Stan, and TruBall make some great releases too. Like other stuff it comes to personal preference.
