Boston, no question. Slane is the least watched DVD in my collection.
Slane pros: Better editing, not as much jerky camera work. Songwise, the inclusion of Angel of Harlem and All I Want Is You, and a great version of One.
Slane cons: Out of Control--worst version of this song I've ever heard. Bullet the Blue Sky doesn't really pack the punch that the "mark chapman" ending had at Boston. Streets was an average version at best, in my opinion.
Boston pros: Until the End of the World--incredible version. Kite--it sounds a bit rougher than Slane, but I personally think the roughness adds more emotion. Gone
, the inclusion of New York (came across better filmed than in person IMO). Great version of I Will Follow (minus the stupid talking in the middle of the song...way to ruin the momentum, just like OOC Slane). Great version of In A Little While, beautiful version of Stay, my favorite version of Bad, fantastic version of Streets... The Fly
, still my favorite version of the song.
Boston Cons: terrible editing in places. SBS was pretty weak. Stuck was pretty weak. WOWY--very weak until the end of the song.
So basically--I just think that Boston had a more unique setlist which rocked. The Slane gig was a much more bland, boring setlist. Maybe if I'd ever been to an outdoor U2 concert I'd feel different. Outdoor concerts just seem so distant, not like the intimacy you get in an arena.
