I prefer take homes if they are reasonably scoped and turn around expectations are around 1 week.
I would rather whiteboard about the design of the app/tool than some random question another engineer pulled out of their ass twenty minutes before the interview and has unreasonably strong opinions about the design and implementation based on whatever source they stole the problem from because they don't actually understand the problem either.
The scope is important. Some of the data science take homes I've seen could be looking for a decent/good-enough solution that takes an an hour to a full-fledged research program that would keep a few FTEs busy for a year.
