Which is the best Forex Robot?

For me the best robot you could ever have is the one built by yourself, I know it requires a lot of knowledge but it's better to have the strategy that worked for you automated than some robots that only promise windfalls and you end up losing everything.

A good place to start though would be to Use MetaTrader4 as a trading platform. It lets you test the robots you choose against historical data and run paper trades or dummy runs with demo accounts.

Also if you are buying Forex robot don't forget to run backtesting that can show is system worth its money.
