I believe that I am firmly in the "accounting" camp. Perhaps that should be taken with a grain of salt because I could happily belong in the camp that likes to buy properties and build bases, control territories and that sort of thing, where it is important.
But I think that when the game often boils down to "kill things and take their stuff" it would be rather a shame if you made that "stuff" abstract. I mean, it would be like making all magical items abstract, "You have now aquired enough loot to be at the +1 magic level."
Now, of course, as has been noted here before, abstracting magic items is completely doable (or maybe it was more rolling magic items into the characters themselves), and depending on the type of game you run, even desirable, but I do not think that I would want it to be the default option. Rather, I do not think it would be that cool in a campaign where "kill things and take their stuff" was the actual motivation.
