I really like my Shubb but liked my G7th Performance 2 as well (until it got boosted
). What I like about the Shubb is that I can put it in my pants pocket and forget it's there.
While I really came to like my G7P2 I had to learn to install it properly for the best sound. It took trial and error to rival the Shubb for sound, but I figured it out. The other thing is that I found the end uncomfortable and dremeled the points round and that improved it substantially. It's almost as light and small as the Shubb.
