Scalene is pretty neat, yes. The memory profiling, however, is more useful when you're trying to find memory leaks. This is a common scenario in web apps, say.

If your goal is to find peak memory usage, which is what you care about in data processing batch processes, Fil is probably a better choice (https://pythonspeed.com/fil).

Having done a serious amount of Python memory profiling work in the past, both Fil and Scalene are useful tools. Add them to your list along with runsnakemem and the high level memory-profiler.

On the time profiling side I highly recommend py-spy and pyflame (a little less updated).
