I've had good luck with the Irwin. It has a nice molded rubber handle so you can get a good grip. Lately, I've been using it combined with some good old fashionde elboe grease to cut into drywall. It's hard work but worth it to keep the dust down and minimize the clean up.
I've also got a "newer" (about 25 years old) Stanley that has the retractable blade, and recently the lever started to stick, and I thought of buying a new one, but came to the conclusion that the old one is far better than most I would buy today, so I filed down the burrs on the lever and housing, and put a new blade in it. Good as new!
