I have to say that I lived in Glasgow for almost 2 years and while I never lived there Paisley didn't have a good reputation. I worked there briefly and wasn't terribly impressed, but it does boast a beautiful abbey right at its heart that my brother in law just got married at, so perhaps it isn't that bad.
Kind of a funny side note about it. There used to be a commercial on TV for a bedding store and it showed couples from all over the world having a 'good time' in their bed, but then there was a couple in bed supposedly from Paisley snoring away!
Suffice it to say that the people from Paisley went on the rampage in the papers to say what a fun loving group of people they really were!
