The correct answer to the original question is in post #2. Except for the really expensive ones like JW Blue, blends are not just a blend of different scotches, they are blends of scotch and unaged grain spirits such as corn liquor. The less expensive the blend the more unaged spirit is it. So inexpensive blends tend to have milder tastes even if the alcohol content is the same. Single malts whiskys can have wildly varying flavour characteristics depending upon where the water is sourced, the types of peat which is burned to kill the grain after germination in the malting process, the type of barrel it is aged in and the amount of time it spends in the barrel.
Expensive blends are blended to achieve a fairly consistent tast from year to year.
If you are so inclined as to be interested, the advantage to single malts is the experimentation with the flavours.
