I don't know about Oanda, but I definitely know about eToro :) At eToro you can trade currencies, Gold, Silver and Oil, and also major indices such as the DJ30 and the UK100 with high leverages and competitive spreads. You can also open a demo account for free and get to know the platform for yourself: http://www.etoro.com/webtrader/start/. Once you're logged in you can see what our traders say about us on our interactive chats or on eToro OpenBook (http://ow.ly/2ULec).
I hope this information was helpful to you in your search of the best forex broker for you.
