I tried GIT today and I must say Coolwater and GIT are almost identical except that Coolwater has a soapier, more acidic, fruity, synthetic 'layer on top'. It's almost as if they are built on the same base. But GIT is a little grassier and deeper. GIT is like the best parts of Coolwater minus all the irritating synthetic notes. Or should I say, Coolwater is GIT with it's good characteristics toned down and some nasty notes added.
Edit:By the way, I was making a choice between GIT and SMW. I bought GIT but after a while decided go back and exchange it for SMW because I already have Coolwater..a disincentive for me to pay such a high price for it. Maybe if Coolwater never existed I would've gotten GIT straightaway and not have any hesitations after that.
