I pretty much agree with all the previous reviews I've read, they are very similar. The only difference was:
Urge is more natural, due to the Real Sugar, and less carbonated. But, that could be due to the fact my bottle was a little dated.
So pretty much exactly what I expected, and I will be reusing the bottle for Vault every once in awhile for fun :D
Conclusion: SURGE/URGE = VAULT
