There are Pros and Cons for both the methods. If you are a full time trader, intraday gives the best returns. Choose swing trading if you are a working professional.

Intraday Trading:

• Gives high returns and the risk too
• Able to learn new things
• Better understanding on market as you trade regularly on same stock/ index
• Suitable for full time traders

Swing Trading:

• Any working professional can trade by spending 1 to 2 hours a day
• Changes of losing huge capital when you are not aware of regular updates
• Gives good returns if you choose the stocks wisely
• As you spend less time on market, there is a chance of missing the opportunities

As per my suggestion, if you are a day trader or swing trader, it is better to keep updated on market and learn new subject. Otherwise your small consistent earnings may vanish in a single day.
