Don't know why you need a man to tell you about drills. They're unisex, doncha know.
It depends on what job he needs to do, how much he's going to use it, and where.
Key decisions are corded Vs cordless, and whether it's for holes or screwing.
My ideal toolbox has three drills. A corded SDS drill for holes in brick and concrete, with rotation stop so it can also be used for chiselling etc. If he's only used a hammer drill up to now, then SDS is a revelation.
A cordless impact driver, for putting screws in. Expensive, but very useful.
A cordless combi drill as a jack of all trades. This gets most use.
My cordless stuff is Makita, and the batteries are interchangeable.
I also have a small Bosch ixi screwdriver that's surprisingly handy.
