In one sense, I do salivate at how a right-handed player can have the opportunity to play LPs from different eras. Being a left-handed player, I do not have that luxury. I will most likely never get a chance to play more than a hand-full of LPs from different ages. While there may indeed be years where some quantifiable factor could be found which would in fact would cause them to be held in higher esteem, I think it would apply only in a general sense. For example, "in general, the guitars made in year xxxx were made with a unique combination that set them apart". But, saying so does not mean the guitars we each have are not the best LPs for us. I have a '79 LPC. According to group think, that was not one of the "better" years for Gibson. And, so be it. But I know this, over the years, I have played that guitar enough to know everything about it. How it responds to each thing I do, exactly where to set the volume on the neck pickup, when to pop the bridge humbucker out of phase, ... all of those sorts of things. Because I have learned that guitar, it is very easy for me to play it. Someone else may pick it up and call it a "dud" and call me stupid for liking it. Not a problem. For me, '79 was a great year for Gibson.
