That's called opinion. Both are important.
If you want to get technical, guitar has more of an ability to go solo than drums do.
Good point.
I think drums are more important though:
Band with the following would do well:
Drums
Keyboard
Bass
Vocals
Band with the following would not do aswell:
Guitar
Keyboard
Bass
Vocals
This is because drums are very distinct and add an important layer to the sound of music. If you take away this it just isn't the same. You can easily recreate guitar on a good keyboard.
Ontopic:
Crafter cruiser and an amp I cannot currently check what the brand and make is. That's it because I only use them for making my songs and I sort out everything else at our band's rehearsal place with my guitarist's guitar setup.
