Both have similar settings and both have intense monster battling action. Perhaps the most significant difference between the two titles is that Monster Collection is only 6 volumes long and is more suitable for people who have little patience because the series has already ended whereas Claymore is still being published and has at least 13 volumes and is more suitable for people who like to read a longer and more epic series.
