Totally depends on you. I used a hand squeezer everywhere I could on the -6A, but while I could squeeze 3/32" rivets all day, 1/8" rivets tended to make my hands sore after a while, so I started to get used to using a gun. With a little ingenuity and practice, I got to where I could set with a gun almost anywhere. But, when I got a pneumatic squeezer with a few select yokes, I seldom have to resort to the gun anymore for universal head riveting. To summarize: I find a gun most versatile but get better (more consistent) results when I can use a squeezer, though a pneumatic is less tiring than a manual one.
