I go through 3 bags a week. I'm on my second of 1.4:
The sugar crashes I would get in previous versions are significantly reduced in 1.4.
The artificial vanilla flavor made 1.3 tastier; 1.4 is easier to prep but its blend of oils and lack of grittiness makes it smoother and slimier.
Unmodified 1.4 digests slightly better than 1.3 for me.
1.3 digested best for me when I added psyllium husk.
I'll be adding that again next batch to test.
