I'm not a big fan of their 80's videos myself. But as far as the best, I'm going to have to agree and say that Zooropa is far ahead of the rest. Numb, Lemon, and Stay are all brilliant. The concepts are funny, visually a treat to watch, and they go very well with the songs.
Achtung Baby, has some good videos, but a few clunkers. WGRYWH is a good video, along with Love is Blindness which is just spooky, and EBTTRT. The Achtung Baby videos all seems to be similar though. The Fly, UTEOTW, Mysterious Ways, WGRYWH, One (bar version), Love is Blindness, and EBTTRT all have concert footage or similar imagery or style. It just seems like too much of the same thing.
POP had some interesting videos to say the least. I love Discotheque, it's just amazing and fun to watch. IGWSHA is another good video along with Staring at the Sun. Last Night on Earth and Please both leave something to be desired. Last Night on Earth has some funny moments, but is basically incomprehensible. Please is just very, very boring to watch.
ATYCLB also has some good videos, but nothing as brilliant as Zooropa, or stunning as AB or POP. Beautiful Day is good along with Walk On. Elevation is fun to watch and has some tongue in cheek humor. Stuck in a Moment (US version), is utter crap in my opinion. The European version is superior in every way.
