I'm partial to peat and peat+sherry is a combination I really dig... but it's a toss-up honestly between #279 (peat+PX) & #283 for me right after opening - they're both really good. I was also fortunate enough to get one of the SCN Westlands (also peat+Oloroso):
The #279 is opening up very very nicely to the point where it has surpassed the #283 (they were about even right at opening for me). The SCN Westland is BBQ & browned butter upon opening - I expect it will get better as it opens up...
#29 is delicious as well but while it has less peat than #279/#283, it's still got enough peat to make it interesting.
I've tried the others at the distillery but haven't opened my own bottles yet.
