It's fairly even in my opinion.
Most of the major sins are also against "man-made laws" in many respects. Lying could be seen as fraud, stealing is a punishable crime, thy shall not kill would apply to murder and so on. The biggest difference however comes from personal restrictions.
Religions however tend to evolve with the times. For example no Christian I am aware of in the U.S. endorses the following two scriptures.
"For six days work is to be done, but the seventh day is a day of Sabbath rest, holy to the LORD. (Whoever does any work on the Sabbath day is to be put to death.)"
"Anyone who curses their father or mother is to be put to death."
Various "interpretations" of biblical scriptures has led to forming many different Christian denominations or sects. Some have more stricter guidelines for daily living than others. Depending on which group one follows will determine how difficult it is to live up to the "ideal" lifestyle. All one can do is their best in any given moment.
Nevertheless within the bible it's stated no one is capable of living sin free! The same could be said of obeying all of a nation's laws.
Ecclesiastes 7:20 KJV
"For there is not a just man upon earth, that doeth good, and sinneth not."
