I can't really comment on the others apart from Calypso but it isn't particularly thorny, many branches are often low thorn. It is however prone to disease and you will likely have near bare sticks in the middle of the season before it leafs out again.

Useful in breeding, need to actively cross pollinate as it's very prone to sellfng and the selfed offspring are often as bad as their parent if they are willing to grow at all.
