I'd have to agree with Ian and Aleksey to a point.
If an Aikidoka fights a Judoka's fight then chances are he may get his butt handed to him, but the same goes for the Judoka who ends up fighting in the Aikidoka's realm.
It's like any other art - If the Aikidoka is unable to avoid a kick/punch combination, chances are the kick/punch artist will win, if the aikidoka succeeds at avoiding the strikes and gets off kuzushi and technique, the tables are turned. If a Judoka does not get a solid grasp on you at his (close) range to apply kuzushi and technique, then you have as good a chance as anyone to pre empt the Judoka's technique with your own. Skill and experience determine marginal variables that can affect this basic dynamic.
I'm not sure if Michael is assuming that the engagement takes place at the typical judo grappling distance. To me, if you're at this point you've alread lost your Aiki initiative. This is one reason why many Aikido techs tend not to work at Judo ranges while practicing in a judo dojo, the maai one is using is for Judo, not Aikido.
I simply cannot agree with that Judo winning 9.9 times out of 10 thing though. It comes down to the practitioner, not the practice.
Just my 2 cents.
