I'm a serious scotch drinker and wouldnt touch many of the ones listed here.
Except this one
If giving as a gift, I might go with the 15year old vs the 10 year old shown, or if it's someone really special - try to find a bottle of the single cask version
I've never met a scotch starting with 'glen' that I cared for.
Johnny Walker blue and silver label are overpriced and I would stear you far away from.
