The word on the street appears to be night two, most definitely, for many reasons--band more settled and comfortable with the sound, the venue, the locals.
And as much as I enjoyed my night 1 experience, I am so jealous of my new friends I met in San Jose who also got to see night 2--because it appears clearly better from the setlist, the reports, and the recordings (first night of Original of the Species . . . Bono playing with lipstick . . . . and on and on)
