Between my two kings, and the corn, the corn is easier.
That may have to do with age and size - the corn is older and much bigger.
The kings seem to be more chill in my hand, but I've noticed that if the corn has a place to hide while he is out, he is much more relaxed. I just let him run up my shirt sleeve. He will hang out and curl up at the elbow. Guess he'd be classified as a "desk buddy." He is usually out for morning coffee while I'm surfing the news sites.
