Ardbeg. First and foremost because Ardbeg never once dissapointed me, not in the OB's and not in IB's, same goes for age and strength. Its always good. As for favorite, Quality like, Ardbeg 1974 For Belgium Edition 1. Scored this beauty 97 wich makes it the "best" whisky I ever had. I dont know how to put it, whisky doesnt get any better then this, flawless, perfect, respect.
For the more payeble and availeble bottlings, the Uigaedail gets my vote. Excellent balance between sherry, bourbon and peat at a high strength but never overpowering. Unfortunately this bottling is bound to dissapear soon

This is one bottling I personally am going to miss badly when its gone.
Laphroaig: 10 CS nice phenols here, or Quarter Cask old school Laphroaig complete with brine, edgy peat and phenols.
Lagavulin: DE PX Finish, Sweet fat sherry combined with the oily thick Laga works like a charm. Also some good peat here. Wish we had the old Lagavulin 16 back...
Bruichladdich: 20 First edition, supreme balance and elegancy. More affordeble: 3D Mhoine Mhor, More clean peat and once more the usual Bruichladdich balance.
Port Ellen: Blackadder Raw Cask On Oloroso sherry cask. The thing with PE is, its fifty/fifty. You either have the heavy peaty ones or you have the cereal malty ones. The ones with heavy peat are greatness, the malty ones IMHO are very weak and dull, not to mention way overpriced.
Caol Ila: Chieftains Choice Medoc Finish though now hard to find, so lets take a new gem: Gordon & McPhails Caol ila 1990 Sherry butt. Excellent balance between FF sherry with an edge and highly phenolic Caol ila. I'm no fan of the OB's here. The CS seems the best choice but after retasting it last week it seems I overrated that one too before.
Bunnahabhain: Only tried the standard so far, wasnt impressed but its way to soon to have an opinion of this distillery.
Bowmore: Any Independent bottling. No favorite here, I dont like the OB's so obviously any IB seems better. The very best Bowmores I tried are unaffordeble so I wont mention them.
However, I'd take an Uigaedaile any time, as a matter of fact, after all this I'll have one right now!
