Since I use Ally banking, it makes it easy to see all of my accounts in one dashboard.
It's easier to transfer money without having to leave the site.
It's Ally, and just as with the banking, they have great customer service and fun quirks about them.
Transferring money, even from an Ally bank account, is difficult to find.
It's not much different over other investment providers and has the same basic layout and functionality.
It doesn't have an investment calculator, to determine how many shares of stocks can be purchased with a set amount, on the stock buying page.
