There are plenty of suitable comparisons from which one can make an educated guess. In general, Macs do better than comparable Windows machines in browsing endurance tests, and Safari clobbers every other browser it has been tested in for battery life (I have _not_ seen a comparison of Safari to this new version of Opera, but judging by its performance relative to Chrome it could be competitive with Safari). Safari, of course, has lots of support for ad blocking short of Apple actually doing the ad blocking itself. I suspect Safari + ad blockers would be the best option across the board (it absolutely rocks on iOS devices).
