I have three long canon Ef lenses: 300, 400, 500. They are great. You should buy this 600 if in the market for one. The cost is well worth it.
Agree with your assessment, the "big whites" are great tools. While similar they all have separate applications. They do share similar high list prices, however buying used or refurbished can make them more affordable. When the shine wears off of mirrorless the prices of this lens will come down also. The latest EF mounted 600mm is an extremely good lens and costs far less. Compare the final results and dare to choose which photo was produced by what lens. "Well worth it" takes on definite parameters of varying amounts that are far ranging.
