Jake, I've never used WY1272 but I've used the 1056 about twenty times and I think it's the most versatile, consistent, low flocculating, high attenuating yeast that I've used. It's generally my goto IPA yeast (although I've used 1968 a few times recently) and I've even made a stout with the 1056 (Sierra Nevada Stout clone) and it came out pretty decent in my opinion.
As far as the reviews on the interwebs, you'll find every answer you can think of, including 1056 being the best/worst and 1272 being the best/worst.
If you have the 1272 in hand than try it. Hope you have your new stir plate with that order and give the yeasties a head start!
I'm sure it'll be great. Looking forward to hearing how the 1272 makes out
