You'll be thrilled (lol) to know that the lambda-tuple syntax isn't in python 3 (!); it does make my examples more concise.
The argument in favor of set-notation being higher level is it's less specific (it doesn't explicitly provide a sequence of operations, just an outcome).
List comprehensions look like set notation but have an implicit procedural translation you have to keep in mind to use them well, so it's a toss-up.
I prefer map/filter/reduce when sequencing has large performance implications but for simple filtering or raw-data-shaping comprehensions read more smoothly.
