I have been a "legal" drinker for 50 years, so yes, I have had lots of experience with various types and kinds of alcohol
As for the whiskies, for years I drank no Scotch or Irish, occasionally Canadian, and my Bourbon of choice were Makers Mark, Woodford Reserve, and Knob Creek. Period. And I always drank them "on-the-rocks" with a splash of water. Once in a blue moon I would have a Manhattan (mixed just with sweet vermouth) or Martini (with Gin, not Vodka)
And then along came Covid ... and I started drinking more ... and suddenly I found more choices of things to drink. A few friends offered me some advice and slowly but surely, I branched out to find some really nice bottles of many different kinds of whisky. Through my travels I have visited a few distilleries, and also found different labels (in local liquor stores) of items I can't find here in AZ
So while I am a seasoned imbiber, I have only about 4 years of amassing experience with the broader spectrum. Now, instead of drinking my whisky on-the-rocks with a splash of water, I drink them "neat". The best glass I've found (and well worth it) is called a Glencairn. And if I find the whisky too "hot" (meaning, the alcohol burns my throat as I sip) I will add a few drops of water
My next "bucket list" trip will be to visit Scotland and visit Islay and The Highlands. And if time and budget allows, a round of golf at one of the courses played in The Open
Cheers! And BTW, your palate being able to enjoy a Perfect Manhattan is more advanced than many other drinkers I know; mine included!
