ATYCLB any time.
Pop is very uneven as an album - only 6 songs really work for me, and Staring at the sun - Oasis influence, anyone? - and Gone are clearly the best songs, and even those two aren't great by their standards. Too much bleeps and samples and they forgot about the SONGS - possibly the biggest irony is that the most straight forward rock songs are the best, and only 3 or 4 songs are really dance influenced. The sound of the band is just awkward many times, it's like they tried to be cool too hard (and trying to top AB and Zoo TV later on, which didn't work).
Like others have said, Miami. (possibly Bono's worst lyrics ever, not to mention "it's the blond leading the blind, it's the stuff of country songs" part, Do you feel loved is something that Even better than the real thing did much better, Last night on earth tries to evoke Until the end of the world but fails. U2 had many better ballads than IGWSHA, too.) Also, IMO Bono's weakest album as far as singing goes, he sounds weak and tired.
Now, ATYCLB is, with its nature of singles material - unfortunately the tracklisting shoves up all the singles in the first half which doesn't help either - also uneven but not as much. Beautiful day, Kite, Stuck in a moment and In a little while shows U2 at its best since AB, and can hold their own ground against older U2 classics well. Clearly the band was inspired by the rise of pop in the charts, and some of the results are great. I like the sound of the album a lot, though I will say the music to POE is something that hasn't won me over and WILATW seems to be indecided between pop sound (keyboards) and rock (the screaming guitar).
Elevation and Walk on, while both being hits, were IMO a bit overrated. (why weren't Kite and IALW singles instead?) Much as people like to pick on Wild honey, it accomplishes it's task as an attempt at a pop song perfectly. I don't always listen to WILATW or Grace, but I do like the lyrics to POE and New York. Even though it's "back to basics" album, there isn't really much stuff that sounds like the 80's U2 (except Walk on and verses in New York, and the "teach me" riff) - there's 5 songs that sound unlike anything they ever did before (BD, Stuck, IALW, WH, Grace), so it's not really like they didn't do anything new. While it's true Bono's voice isn't what it used to be, this time at least he goes for some of high notes again (
to Kite) and sings with passion that wasn't present on previous two albums - except maybe Stay on Zooropa.
8/9 songs work for me.
it's very personally touching to me. POP gives me a headache, sorry.

I Just can't get away from the drum and bass
