Its worth noting that whent he S2 Batch 2 first went on sale, BTC was significantly higher (I think it was only ~6.2BTC when i ordered). Makes the price comparison more reasonable.
Also, it seems like the S2 can achieve 1.15TH/1.25kW without much more than an extra PSU wattage. If so, you now have the same hashrate as 6xS1, but for about 1.1kW less power consumption
