Having worn out more than one set over the years: Most aircraft mechanics have gone to the smaller ones, however, the larger ones are easier to use. The added flex of the longer handles makes them easier to lock, but the smaller pliers are better for tight areas and easier to carry around. All else being equal, and for the job of wiring up knockoffs, I'd go with the full sized pliers. If wanting to keep the tool box light, the smaller one are fine too.
How's that for a definitive answer?
