In my experience, scottish drams are best enjoyed as single malts, and irish drams are best enjoyed as blends.
I think it's moslty due to the smooth character of Irish whiskies due to the triple distillation.
I just think most of the scottish blends are crap, JWR, Ballantines, Chivas, J&B, Cutty Sark, Famous Grouse, neither of these can tickle my fancy.
Tullamore Dew, Jameson, Bushmills are all pretty good I think.
To every rule there are exeptions of course,
I quite enjoy drinking Té Bheagh, I like anything up and including green label.
And paddys is just drain cleaner.
