I recommend you go with the classic challenge. WHY? Well since you raised the question about which one is better for you, I assume that you don't completely understand the trading rules and there is nothing wrong about it… you will get there sooner than you think. That's why I recommend you to take it steady and slow and spend more time trying to pass the challenge. That's how you will master the trading rules which are essential in the latter phase when you will start trading with real money. Remember, Rome was not built in a day, but it was ruined pretty quickly. The same is true with trading!
