Anyone see the documentary "A Band Called Death"? It's about an all black Rock n Roll punk band from the 70s that made some great music but could not get their careers going because of their band name until decades after they disbanded. Very cool, check it out.
That's a whole discussion in itself but this is always who comes to mind for me. I think it's mainly a generational thing as well.
Definitely a generational thing. When I think of pop punk, these bands come to mind:
Big Drill Car
Down by Law (1st record)
Evergreen (more emo than pop)
Green Day (1000 hours & kerplunk) they suck major monkey balls now
