Interview (I worship everything Baron does and Interview is no exception. The most stylish magazine out there. When it comes to other magazines there are always a few things I'd like to change on a cover, layout etc but with Interview everything is just so perfect and reflects my taste percisely every month).
W (Not so much now as pre-2009 but W is always a must-buy for me bacause it always has fun articles and tidbits plus I've never actually seen a really bad ed from them. That having been said I really miss the old W with its really long editorials and amazing design - favorite logo ever - and edgy celeb covers).
Two years ago my third choice would be Vogue Paris, because again their design was out of this world, the eds always appealed to me and I felt that just by reading the pages with the cinema, art, music I was ahead of everything. Now, I guess I really like Love because every issue is pure editorial eye-candy, plus the size and paper are so luxurious, it feels like a collectible coffee table book.
