Shinedown: 4 albums, highest one charting at #4, combined sales of 3 million in the states.
Godsmack: 5 albums, last 3 consecutively debuting at #1, combined sales of 8.5 million in the states.
Last headlining tour in support of a new album, Shinedown didn't even sell out a 1,500 capacity club in Rhode Island, whereas Godsmack had no trouble putting 6,000 asses in the seats of the Tsongas Arena.
In no way, shape or form is Shinedown a bigger band than Godsmack.
