Another between epoxy and gorilla glue in my experience, is unless you have avery tight fit between the parts, the gorilla glue is more flexible than epoxy when it cures. For joints that are subject to vibration, this could be good, but if its a high stress joint, the gorilla glue may eventually give out. I like the fact that epoxy soaks into the grain of the wood before it cures, making for a better joint.
