I am unfamiliar with much of today's ki society though, so I plead ignorace beyond this observation.
I find it hard to get into their seminars being from the Aikikai.
What exposure I have lets me think that Aikikai has the technical proficiency and waza application but the Ki-Society has the connection and energy flow. Perhaps the gestalt is that the sum of the two together is greater than the sum of its parts alone.
I still try to sneak in whenever I can.
