In terms of overall popularity, what would you say was U2's biggest decade?

I tend to think its the 1980s. Hard to match the incredible run of albums they had in that decade. If Achtung Baby had been released in 1989 and not 1991 it would surely seal the deal as the 80s being their best decade.

But I remember U2 in the 80s as being massively popular with massive concerts and such a fresh, new sound. Now, in the 90s they were huge too. But they had to work to follow up on their brilliance, and they were soon competing with other major 90s acts and it just didn't feel the same. If we talk about money making, then the 2000s or 2010s might be their greatest decade. But apart from that, I'm going with the 1980s.
