I've chrono'ed BOTH, and they are almost exactly the same "power factor". I can load up a magazine, alternating one of mine, with one of the factory. The 115gr stuff is MUCH "sharper", with more recoil. My 147gr stuff feels soft as butter in comparison. The heavy stuff is more expensive, but its worth it for me. Of course, I shoot competitively (GSSF and IDPA) and looking to get my sights back on target quick for that second shot most targets require. If I was just "plinking" all the time? The 115gr would be more than satisfactory, plus cheaper.
As a bonus, 147gr is alot quieter, too.
