Generally, between these three religions Islam is considered to be the middle ground between the strict teachings of Judaism and the laid back views of Christianity. In Islam you will learn that moderation is key to this religion and regulations are set so to be easily incorporated into your life with little hardship.
Lastly, the greatest aspect of Islam is that there have been absolutely no changes to the religion. You will find Islam to be the exact same across the entire world and across all nations. Every Quran is the exact same, there is no changes to it. This is said to be the greatest attribute to the religion.
