The first one is fine  :-)

Any scan that is long enough for you to actually time it should be good.
Larger collections are better since they're more likely to spend more
time (in master) sitting doing SQL queries, but one that takes a minute
or two should be just fine. Plus, being able to spot if anything is
wrong (it really shouldn't be, as I did extensive testing for
correctness of this result vs. the SQL method during development) is a
bonus.
