The energy numbers you list are the product of a mathematics formula and are useful for comparisons but you can't put the effect of bullet striking flesh in a nice neat formula, wrap it up with a bow and draw conclusions that are irreversable. Generally speaking, the formula favors velocity and could lead us to discount the performance of long heavy bullets at modest velocities such as 160 gr. 6.5s or 175 gr. 7mms. Proven game getters, everybody say amen.
With premium bullets that hold together well at high velocity, such as you list, the 225 does have a velocity advantage and may be the better choice if you anticipate long range shots.
When using lower cost bullets, and perhaps shooting over shorter distances, the 250 grain bullets at more modest velocities, might be a better choice in some circumstances, where deeper penetration is desired.
In recent the years the overall quality of bullets has improved dramatically, the lighter weights in any caliber will usually perform about as well the next step up did twenty years ago and they usually come with a few benefits such as higher velocity and maybe even a little reduction in recoil.
