Though my parents are both from North (Aomori and Hokkaido), I was born and brought up and am still living in Tokyo, Dave.
Many of my colleagues are from Kansai area, also I have daily contact with customers in Kansai, so it is interesting for me to see the differences in intonation and some different usage (especially ending of phrases/sentences) between Kansai ben and Kantou ben.
While some ways of speech by males from Kansai may sound a bit harsh, generally I find intonation of Kansai ben sounds softer and milder to my ears. I cannot use it myself, but I like it.
