In my personal observation, Major League Soccer (MLS) is indeed competitive. The league has demonstrated significant growth over the years, attracting high-quality players from around the globe. The playing field is also quite level, with different teams winning the championship in recent years. Moreover, the financial investments and infrastructural advancements in the league are noticeable. So, from all these perspectives, it's safe to say MLS has become a highly competitive soccer league.

Football leagues have a packed schedule and they often struggle to fit in all the games they need to play. This means that they often have to play multiple games in one week. However, there are some drawbacks to this, and it can be hard for the players to stay in peak physical condition when they have to play multiple games in a single week. Additionally, the quality of the matches can suffer, as the players are often tired and unable to perform at their best. It is for these reasons that many football leagues opt to only play one game a week, allowing the players to rest and recover, and ensuring that the matches are of a high quality for the fans.
