I like the Datrex bars the best. I just had some mainstay and yuck but edible. MREs are fairly disgusting IMO.
To be honest I have a jar of honey, peanut butter, and minute oats for my bob. I always eat the Datrex bars because I love sweets and wouldn't normally buy anything with suga.
The pb and honey I'm not tempted to eat, but look forward to it in case of a delicous emergency! MMMMMmmmm! :-)
I plan on replacing it yearly and its about $10, plus doesn't go to waste.
