To clarify this, because it may come off wrong. It doesn't matter the spirit type, but there is a huge market for "smooth", essentially booze that is really easy to drink, mellow, soft and which doesn't hit you over the head with the reality that you're drinking a high abv product. Johnnie Walker Blue is the king of that. So if you want that, you'll probably like it. For the record, Platinum is almost the same to me, and is a lot cheaper. Green is the JW I like best. Black is tolerable, but overpriced (marketing $). Red is undrinkable swill.
There are bourbons in this category, like Basil Hayden. I don't get it, but I know folks who love it. Sazerac rye is as mild as rye gets (and is still pretty good). I'd say most Irish whiskey emphasizes "smooth", they are only now producing some things with a bit more assertive flavor profiles. Triple distilling removes some of the more aggressive notes. Rum is all over the map, it's too complicated a category. Cognac sold in the U.S. is mostly in the "smooth" category. A lot of easier to consume products cover the lack of aging with sugar. Southern Comfort, Fireball, and everything else like that. Some rums do that as well, be careful buying rum. Gag me with a spoon.
Long story short, if you really like Blue, try Platinum. It has an 18 year age statement and should scratch the same itch.
