Sorry, 243, but that is Power Factor, which is momentum in non-standard units; not energy.
As to the OP, it depends on whether you are as sensitive as The Princess And The Pea.
Some people say they can tell a difference in such things, and go into discussion of acceleration rates. I can't.
I might notice a muzzle blast effect, higher chamber pressure leads to higher muzzle pressure leads to louder blast. Which accentuates recoil. I was chronographing 9mm the other day and while Blazer was only slightly faster than S&B, it was a lot louder and had a perception of greater kick; although the computed recoil was only 3.5% more.
