As Tom said, GBs are OK, but one of the J-men looked at me at one of my first jobs and told me
Throw those things (GB linesmans pliers) in your truck, or use 'em around the house. For this job, buy a real set of pliers (Klein)
+1 for Klein, Ideal, Greenlee. Stick with a brand name - there are a few brands that contract with the "big 3" listed above (many Craftsman electrical hand tools are made by Klein, for example), but generally stick with the known names.
Consider the extra money for the Journeyman series, and the "2000 series" from Klein. The Journeyman feature is composite handles that make squeezin' easier, and the "2000's" are hardened to cut steel (nice when the "wood apes" leave nails sticking into your work area... or you need to cut BX/Greenfield or tracks for can lights). Just my $0.02.
+1 for the Klien 6-in-1 tap and the 10-in-1 screwdriver.
For lighter weight, consider the "reflex" (?) stripper/cutters from Ideal - they're a composite design - very lightweight. Not sure how they'll hold up to long term use, but worth a look.
