If I(8L) equals I(8XL) then Total power equals, but shaft power differs.
And based on motor size and guys feedback I will say that I(8L) should be higher.

What do you mean by shaft power? I'm guessing you mean power output, as opposed to power input. With the same power input, both the 8L and 8XL will have very similar power outputs. This will depend on how efficient either one is. Without specific data it is hard to say which will be more efficeint (on 12 cells) - but personally I would say that the 8L will be more efficient at 30,000rpm than the 8XL at 23,000rpm. The difference will be fairly small though.
I think/hope we are both in agreement now
