its way worse for kiss because of the makeup/stageshow/aggressive marketing (and gene's big mouth). if they had dressed like every other 70's hard rawk band and never did what they did image-wise, people wouldn't hate on them as much, and would recognise them as a good band. their first 4 albums are chock full of good tunes, haromony vocals, and playing. IMFO. as far as their decline in quality over the years, i think its the same as any other long term band (stones, aerosmith, zz top, etc).
