Gotta say that of those currently in the top flight Newcastle would be by far my favourite away (Though haven't been to Spurs, Arsenal or West Ham since they moved or renovated their grounds).
Great view, plenty of transport close by and a great range of good pubs.
Hate anywhere you get a worms eye view.... used to enjoy Blackburn, but that was probably more to do with the Fernhurst than Ewood, Bolton is a mare, Derby get extra marks for having a smoking pen at half-time for away fans, Klanfield and Goodison should be in a museum, Old Trafford is great for watching the Ashes, Vicarage Road is amazing that it is allowed to open with the size of the concourse (Though the Wellington is a great pre-match boozer)
