Just talking taste here, not any claimed caloric, health, nutritional, etc. benefits (or lack thereof).
Personally, I like the Reduced Fat Wheat Thins and Triscuits better than their regular versions.
I think 2% Fage is better than the regular full fat version.
I like Baked Lays better than regular Lays.
I like Baked Kettle Chips (esp. the Salt & Vinegar) better than the regular version.
