It is all about what you are trying to achieve.
In most cases folks who are building the Home Theaters want to have theatrical movie like experience, hence the rows of seating look like in real movie theaters. There is nothing wrong with getting individual recliners, but I would say that this would be more for a media room that is used as a multipurpose one where you not only watch the movies, but also socialize, play games, etc... This gives you more flexibility of arranging your seating and placing any kind of consoles, coffee tables in between the seats, or simply putting the seats individually in various places in the room.
