In terms of trading and executions I like them both. Never had a problem with Ameritrade. Used it for a few years. But Etrade has been my go-to broker for years (I opened my first trading account with them in 1996). I have used others too. I highly suggest you stay away from the little guys and go with either of these two. Etrades's trading platform (Pro) was much better than Ameritrade's and that is why when I decided to consolidate and use one broker I stayed with Etrade. Don't know if Ameritrade is better now and if they offer everything Etrade Pro does because it has been a few years now since I closed my account.
