As a former operator of the sturdy K, and a current operator of the J, I have a great appreciation for the merits of both types. It is hugely entertaining to hear this 'I've got a steering wheel and you haven't' banter. Makes me laugh!
Facilitator is correct (and incidentally does have the credentials). The J can do the job, I have seen it. It can do the job when the strict set of rules goes out of the DV window. I have seen that too.
And as for Darkside2, have you ever flown on a J on a Tactical mission profile? If not I suggest you try it. But then again I guess your mind is already made up judging by the tone of your posts. No seat, no like it...
