I would slightly disagree, caviar and a beautiful view do feel great in the same way as tranquility, afterall pleasure reach it's limit in removing pain,
I have the same reaction, Wbernys, and I would be alert to the direction that some writers seem to take that tranquility does not only not "feel great" -- but that tranquility is not a "feeling" at all. That's how "they" (not referring here to Max) argue that tranquility is not a feeling at all.
This is no doubt a complex subject, so I think one of the ways to help sort it out is to play out the logic ruthlessly, and see if the logic results in an absurd conclusion. The Epicurean texts are replete with references to not even being able to know what good is without reference to the normal sensory pleasures of life, so if we hold fast to that and rule out any construction that the Epicureans didn't really care about normal pleasures because all they wanted is "tranquility," that should be a good way of avoiding an absurd result.
The common sense "pleasure means all types of pleasure" perspective can easily accomodate the value of tranquility as one among many important pleasures, but the "tranquility above all" perspective cannot coexist with the great weight of the authoritative records. Had "tranqulity above all" really been Epicurus' teaching, the Ciceros and Plutarchs and Epictetuses of the world would never had raised a finger to oppose him.
