Although I did not attend Manchester I kept it on my iPhone because of its unique sound. It has the best balance of instruments. It is most striking on HFB, on no other show I can hear Guy's synth as clearly as this one, this gives more emotion to the song !
I attended RAH*2, Paris*2 and Nice, and I have to say that Nice has an edge for me: best TR solo, best Sultans, original and great Speedway, amazing KOG, a must have ! Mark was most energetic that night !
Paris second night has the longest TR solo (but may not be the best).
There are all very good, base your choice on the set list and comments on specific songs like TR...
Maybe don't go for RAH1 and Paris2, a lot of people found them less good than alterate nights.
