I'm a fan of Partitions. I usually hunt with high speed rifles (25-06, 7mm mag, etc), and I've had no issues with expansion. They don't expand quite as well as some of the others but they have much better weight retention than some of the others. That is big to me because with high power rifles sometimes you don't have much left of the bullet. That and every once in a while my bullets don't find their mark and I hate to see a big chunk of meat go to waste because I'm shooting mean bullets. Same reason I don't hunt with polymer tipped bullets.
I don't know anything about the CT bullets.
