Which is better - flight or fast train from Beijing to Xian?

It takes around 2 hours by flight and 5.5 hours by high speed train. The second class train tickets are more cheaper than that of economy flight. If you want to save time and cannot endure the long time train journey, you should choose flight. If you want to experience the high speed train in China and enjoy the scenery along the way, the train is a better choice.
