I used 1272 for ten years as my house ale strain and a few months ago I made the switch to 1056. 1272 has higher ester production and flocs better. Diacetyl was never an issue unless the beer was prematurely cooled. 1272 is a very reliable strain and makes great American ales.
I switched to 1056 because I wanted a strain with a cleaner alcohol character. DIPA and other big beers are part of my regular portfolio now and I found the higher alcohols to be distracting. I do have to wait a little longer to crop. All of the beers are unfiltered and I am still achieving great clarity with the less flocculent 1056.
Hope that helps.
