Agreed, I can think of many bands from Germany that are better than this band.
Scorpions
Rammstein
Accept
Doro
Edguy
In Extremo Guano Apes
Grave Digger Michael Schenker Group
Helloween
Running Wild Warlock
Die Ärzte (even though I can not stand this band, I really do not like them)
Die Toten Hosen
Böhse Onkelz
Not all of these may be well known outside of Germany (except those that are in bold, they are popular world wide), but they are better bands.
