The fact that many people call so many different songs 'their favorite' is telling. In a very good way. My favorite is 'Original of the Species,' which (to me) almost sounds like three or four different songs in one. Indeed, the last minute or so of this song transports me to a whole other level...and echoes of 'Where The Streets Have No Name' resound.
For me, there are more enjoyable songs on this disc than perhaps any other by U2. And the songs I feel are somewhat 'lesser' are growing on me after each listen.
Since one of the comparisons being floated is between 'Bomb' and 'ATYCLB,' my vote is exceedingly in the camp of 'Atomic Bomb.'
