Again, my experience does not indicate that either group produces noticeably better (or worse) aikido.
My experience says the same thing, but I would caveat that, all things being equal, Ki-Society is more poised *technically* to incorporate internal strength because there is already some there, even though, IMO, it's not taught anywhere near as clearly or extensively as it could be. Also IME I find far too many Aikikai people to be stiff and muscular.... no offense (I'm now an outsider looking back in and exempt from the wrath of "seniors"). Being stiff and muscular is almost impossible to change for most people. If someone is able to change some things, I'm always quick to acknowledge it; if they can't change, I'm not going to be the diplomatic bump on the log that pretends out loud that everything is OK. That's not fair to beginners and believe it or not I still identify with beginners getting caught up and harmed by political BS.
