I think it depends on how you look at it. As far as chart success you would have to say "no" they are not as popular now as they were back in 1987. They had two #1 hits in the US with JT and have only cracked the Top Ten, I think, twice since then with Discoteque and One.
Just some minor corrections here...
First, "Mysterious Ways" and "Desire" were also Top 10 hits.
Second, the charts are constantly changing. Back in 1997, for example, a song couldn't chart until its CD single was released. However, now, songs chart on airplay alone as CD singles sales were relatively low and sometimes not really indicative of a song's success.
"Vetigo" forced Billboard to change their charts again. "Vertigo" was a Top 40 hit based on airplay, but with over 300,000 downloads, it was so wildly popular on-line that Billboard is now including legal downloads when considering a single's chart placement. This new procedure was just implemented and as a result, "Vertigo" leapt nearly 20 places on the charts. Had this been in place in "Vertigo's" prime, U2 easily would've had another Top 10 hit.
With that in mind, it is arguable that U2 is as popular now as they were in the JT and AB days. However, in the JT era many people were just learning of U2 - so there was that extra "magic". U2 were finally the "next big thing" and people paid attention. Plus, they were young and different. With their longevity, some of that "magic" has been lost. Therefore, I'd say U2 are still going strong, but in terms of sales and charts, not quite as good as in '87.
However, the question asked about overall popularity. And since U2 has been so successful for so long, I'd say they are more popular than ever. They have fans from the 80's, 90's and the 00's. Even those who didn't like "Pop" or the newer works are still fans and are still buying the music and going to concerts. Everyone (who pays attention to popular culture) knows U2 - especially Bono - by now. So I'd say that definitely U2 are at their potential peak.
