The 8th is my favorite.

For me Mahler is so great because each symphony is a gargantuan monument of the human soul, and speaks millions of words. They are all so individually characteristic.

Historically Mahler was important in the transition into the 20th century as his symphonies began to break down the essence of tonality and paved the way for schoenberg and many others.
