I've heard a lot about Mods vs Rockers in the '60s. But can either side reasonably claim to have 'won', either overall or in any of the significant individual 'battles', e.g. the 'Battle of Brighton'?
First I would like to define the terms Mods and Rockers, according to Wikipedia:
The rocker subculture was centred on motorcycling, and their appearance reflected that. Rockers generally wore protective clothing such as black leather jackets and motorcycle boots (although they sometimes wore brothel creeper shoes). The common rocker hairstyle was a pompadour, while their music genre of choice was 1950s rock and roll, played by artists like Eddie Cochran, Gene Vincent, and Bo Diddley.
The mod subculture was centred on fashion and music, and many mods rode scooters. Mods wore suits and other cleancut outfits, and preferred 1960s music genres such as soul, rhythm and blues, ska, beat music, and British blues-rooted bands like The Who, The Yardbirds, and The Small Faces.
I will base my opinion on what subculture is still popular today. I think that Mods music genres and culture is more popular today. Mods covered larger music genre so it has probably touched more music fans than Rockers.
And Mods fashion style seem to be more common today (elegant suit, short and flat haircut ) than Rockers (motorcycle leather protections, pompadour hairstyle...).
Mod culture had his revival in the late 70s and in the 80s and some Mod bands from this period were still active recently.
Also recent brit rock seem to have more influences from the Mods than the Rockers. Here is a clip from Lostprophets that makes obvious references to Mod culture (scooters, suits, haircuts..).
