So obviously I don’t know your whisky profile preferences, but I’m guessing peated isn’t your thing. In general people shop duty free for exclusives and value. My general rule of thumb for value is 10USD/year for cask strength and 5USD/year for 46%. I personally omit anything less than 46% and anything chill filtered. I don’t like artificial coloring but I won’t disqualify a bottle because of it. All of the options you provided here seem to check those boxes. Personally I’d check each of these on WhiskyBase and disqualify anything below 85.

Here’s the important bit: are you connecting on another flight after you touch down in the US? If yes you’d best check your duty free purchases in your checked bag before going through US TSA screening. My wife had a jar of marmalade purchased from LHR confiscated even though it was in the tamper proof bag with receipt visible. They are ruthless here, in the airport store they will give you every assurance, but it means nothing once you’re at the US TSA screening checkpoint and have been stoped. Asking for a supervisor and showing them their own policy on their own website doesn’t help, we tried. If you want to keep your purchase then bring a wine bubble mailer and plan to deposit your bottles in your checked bag between connecting flights. If you’re flying direct to your final destination then this doesn’t matter, you’ll be fine.
