well, even though they are the Backstreet Boys of punk, i think they put out the best music. many punk bands can only carry out a tune for one or two tracks per album but these two manage to make albums full of listenable music. there just seems to be something lacking musically in the 'scream a lot, pound the drums, wail on the guitar really fast, anti-government' songs. some bands are better than other for being listenable and holding true to punk- bouncing souls, dropkick murphys, and sometimes Rancid are the best examples. there are also a lot of fringe punk bands that also sound a little too Pop for punk but get classified as punk anyway.
