Which brokerage do you feel has the best desktop and mobile interfaces?

I have been a 10 year Fidelity user (I've used others, Scottrade, ML, and TD also) and I found I like Fidelity's interface best. I liked their desktop, mobile, ATP, and trade interfaces however, the new interface they are pushing is garbage. It creates so much dead space that you have to scroll more and select more tabs, all to get less information. Now that they have forced this subpar interface change, it seems like it is time to take my money somewhere else, assuming there is a brokerage with an interface that I like better. Any recommendations.
