Which one is better to trade with, that one would likely make more money on? I am thinking of going on a trading course so I can start trading to make some more money. Is this sa good idea, or is it unrealistic? What's the difference with trading one and not the other? Or should I trade both?
yes a course will probably give you enough knowledge to confuse you really. too many people regard trading as get rich quick scheme. see here

for good advice.
There is no easy answer to this question. I myself know a little bit more about options than I do stocks. However, you could try both if you have the means. I get most of my information from here: http://www.simpleroptions.com/public/Day-Trading-AAPL-Options.cfm. My most recent study is on Day Trading AAPL Options.
