Well, I have one on each arm right now and just voted for L'eau, but that was more to keep it close and see the results. I think both are exceptional and each is like nothing else I know. So for me, perhaps, it is a tie. One thing I do think is different is that the drydown of L'eau is very refreshing but has a "warm" feel to it, like dry grass, whereas SV's drydown is "cool" like a mojito. L'eau also seems to develop a lot more, while the citrus-mint of SV is pretty linear. Both seem to last well on me if I apply enough to start.
