Which should you buy?
What decides this is not the score, it is the display. Halliday G2 shows information on the lens, while Oakley Meta Vanguard shows nothing and answers through the speakers. Reading is far faster than listening, but you pay for it in battery, price and discretion.
Oakley Meta Vanguard wins the overall score by 0.5 points, but that score averages six criteria and you will only use some of them.
Battery is not close: Halliday G2 lasts 12 hours against 9 h for the Oakley Meta Vanguard. The reason is the camera: recording is what drains the cell.
Oakley Meta Vanguard has a camera and Halliday G2 does not. If you want to capture without reaching for your phone, the comparison ends there.
Both have manufacturer-confirmed language support.
Halliday G2 is 17 grams lighter, which you feel on your nose after eight hours.
On price, Oakley Meta Vanguard is 100 $ cheaper.
Watch the warranty: Halliday G2 offers 1 year and Oakley Meta Vanguard offers 3 years.
