Isn't most of that content the same thing? Once you get the Legendary level of gear it's all shades of the same. I haven't really seen much difference between the rifles (outside of their type), only different names and maybe a slightly different picture of it. The stats are the same. Even the two Exotic armors I got had the same stats only different names. The game content does plateau out.
The weapons, especially exotic weapons, function differently. They sound different, look different, have special exotic upgrades that no other weapons get.
