Does it matter? I don't care what Fidelity, Vanguard, etc run under the hood, I have no loyalty nor switching costs.
Vanguard's interface is garbage, plain and simple, but they have the lowest cost index funds; I'd use paper and pen to correspond with them if necessary. I moved from Betterment, who has a very delightful iOS app and web interface, because the fees were lower at Vanguard.
