70's stuff had a more rock 'n' roll groove to it. The 80's hardcore, not so much.
I prefer the more rock 'n' roll groove. Because you just can't tap your foot to a hardcore song. It's just a blur of noise after a while.
Not saying any of it is no good.
whatever i like, i dont sort it. but mostly 80-85.
i've started listening to 90+.
I don't really care much for years, so to me its "punk rock vs hardcore," so I'd say 1970's.
"Hardcore" is kind of a big pissing contest to see who can be the most, well, hardcore! But I'm just going off the majority, I know all hardcore isnt like that.
