Fourth try

Watching and listening to a good concert at home is definitely much better than attending to the same concert.
First of all, watching the concert at home is easier, you do not have to travel or queuing queue for a long time to get a good place or a seat (if seats are offered). However, you can be more comfortable at home, laying in your favorite sofa or eating your home-made food.
Secondly, concerts are ususally crowded and people are really excited there, which means that sometimes they do not behave properly. The most common behaviors you can find in a concert are yelling or whistling loudly and of course being pushed. In my opinion, all this these behaviors are strongly unpolite very impolite and create a bad atmosphere.
Last but not least, it is very difficult to listen hear clearly in a concert, because the facilities are not usually built to offer a perfect sound in every seat. On the other hand, nowadays you can enjoy an amazing quality of sound (or sound quality) at home for a reasonably priced sound system.
Paying for attending a concert it is not really worth it, instead, you can acquire a dvd for less money and you will have the concert forever.

Very well written Mario. My corrections are in red and my suggestions to sound more natural are in blue/grey.
