Luke seems to be the most descriptive about main events, the birth and death of Christ. However, if you don't read them all together then you aren't getting the whole story. They all complete each other and fill in the blanks where others have left things left out. The gospels are amazing in themselves just because they tell about Jesus' life on earth.
That's really true, Arabus, all listed are best for different reasons, I picked Matthew because it's the most balanced of them IMO, but I like them all.
