This is a great write up from Kal @ the electric brewery comparing US-05 & 1056.
This might help!
Unlike Kal, I can tell the difference.
I can too...and MUCH prefer what 1056 delivers.
+2. I'll use S-05 occasionally for short notice brewing, but I can tell the difference. To me S-05 is slightly more powdery/less flocculant and slightly fruitier than 1056. Not a lot but distinguishable.
EDIT - Having said all that, S-05 makes a perfectly good beer. I just prefer 1056.
+3, US-05 is my backup yeast
