Different manufacturers use mileage ratings differently, so you can't really compare between brands. Since you know how much antenna gain you need thanks to the TVfool report, you don't need to worry about mileage ratings.

Gain and beamwidth are complementary - higher gain implies narrower beamwidth. The gain/beamwidth figures for the Winegard and AntennaCraft make sense. When comparing gains, be sure the units, or reference, are the same. Some gains are referenced to an isotropic antenna (dBi) while others are are referenced to a dipole antenna (dBd). 0 dBd is roughly equal to 2 dBi.

Boom length depends on the designs of the VHF and UHF sections. Again, different manufacturers may use different designs, so you can't use boom length to tell everything about performance.
