I used to use Cliff Bars for part of my nutrition. Usually towards the end of long rides where it's not so bad to take in some protein to start recovery. I got sick of them too though; the taste, and the texture. They are more of a snack food for lower intensity stuff like hiking with all the fat, fiber, and protein, or just a "lifestyle" food frankly.

I mostly replaced them with Nature Valley crunchy granola bars for something that is ready made and cheap. I have not had issues digesting those, or rejecting the taste after many hours on the bike.
