I've been to quite a varied selection and tried to pick them for reasons that might result in excellent shows. I've not been disappointed once.
My shows were
Boston - May 26th
Boston - May 28th
Twickenham - June 19th
Dublin - June 24th (1st night)
Barcelona - Aug 7th
MSG / NYC - Oct 10th
I can easily rate these myself and my opinions seem to have tied in with the general feel for each of the gigs. All I know is I've seen 4 out of 6 amazing shows and the remaining 2 were execellent but not as good as the others.
1st - MSG - 10th Oct
Best opening of the tour, best crowd of the tour, Bono was on fire, the band were on fire, the setlist was awesome and it was everything I'd ever wanted from a U2 gig - my 56th gig in 22yrs and in NYC - brilliant!!!
2nd - Barcelona - 7th Aug
Best outdoor gig - biggest stadium in Europe. Lovely day, massive crowd who went absolutely nuts, band were great, Edges birthday was great and they played Party Girl - brilliant!!
3rd - Boston - 26th May
My first USA gig which was a lifetimes dream, lived up to all my expectations and the crowd in Boston are a full on Irish crowd so it had that special feel. MSG stole it though.
4th - Dublin - 24th June
Apart from the fact it pi*ssed down with rain the entire time I had a blast although I have seen them 3 times now in Ireland and Slane cannot be beaten
The other 2 were excellent but nothing special.
My best all time list to put this in perspective
1 - Slane Castle - Elevation
2 - MSG - Vertigo
3 - Barcelona - Vertigo
4 - Dortmund - Love Comes to Town
5 - London - Unforgettable Fire
6 - Frankfurt - Zoo TV
7 - Dublin - RDS - Zooropa
8 - Aylesbury (my hometown) - October
9 - London - Joshua Tree
10 - Cologne - Achtung Baby
Thus ends the ramblings of an old timer.
