I am not sure who is the 'best' group. But I will offer the group that made probably the biggest mark on Rock music during the 90's:
Nirvana
I will not admit to being a big Nirvana fan, but these guys created songs that has inspired much of music for the last decade (and probably years to come).
There is something about their music that touches a raw emotion in people that few groups have ever been able to duplicate. And I am not a big Nirvana fan at all. But I can appreciate their composition.
Nirvana was like Queen was in the 70's. Queen in the 70's really influeced pop music through the 80's. The late 70's songs We Will Rock You and We Are the Champions stuck a nerve similar to the nerve that Smells Like Teen Spirit struck in the 90's.
