Gearing ranges are almost identical in both. Bigger chainrings are usually slightly more efficient, though I don't think that a mere mortal can notice it.
Cassette gear spacing is better on the sram one as it has one more cog (that's more noticeable). IMHO, that's the only advantage.
I wouldn't spend $200 for that though. Well... to be fair I wouldn't spend anything on an electronic groupset.
