For me.. overall.. Maiden are better than Saxon but of the later years i think Saxon write better real Metal songs.
In the 80s Maiden were kings but from the mid 90s onwards Saxon have released some strong albums and i think people tend to over look em.
It seems to me that Saxon lost some street cred around the mid to late 80s but did manage to turn it around from 'Dogs Of War' (1995) onwards.
In the early 80s Saxon and Maiden were pretty much neck n kneck but Maiden remained consistant where as Saxon didn't..
