From what I remember reading around over the years, the difference in actual performance between the two is minimal. Neither are all that great, so why not pick the one that offers better shootability and hit probability. A good hit with a slightly less powerful round, is always better than a poor hit with a slightly more powerful one.

Beware of associating with "Cheap" Squirrels. They tend to be very narrow minded, hypocritical, and will gag you if you question or disagree.
