If you are happy with your current bag, stay with it.

And this goes for the whole kit. And the kaboodle. ;^)
Recently there was one of the “critique my gear list” threads and the OP explained that he knew about the lighter options and had used some of them but for various personal reasons opted for heavier stuff for comfort, packing flexibility and reducing the futz factor. Overall the list was complete.
There was a lot of stuff on his list for which I would have chosen something much lighter in weight—for instance, a 52oz (!!) pack—but his rationale for carrying various items was sound.
So if somebody wants to carry that much stuff it’s none of my business. On the trail I don’t proselytize about UL but will definitely opine if a heavy-hauler brings it up. But, as others have noted ad infinitum, this IS BackpackingLight and people are going to recommend lighter stuff if you ask.
