The bunkhouse floorplan is fairly standard between manufacturers so you have to get picky when looking at the same floorplan and two manufacturers.
I have a 2013 3011 which isn't a direct comparison but things that I noticed when I purchased my Forrester that might compare with the one you're considering are:
Air suspension in the back
Rig was in alignment from the start and was a breeze to drive compared to my old 25 ft C.
Quieter as you already mentioned but there is more to it than the insulation. The brackets and mounting hardware in my forester are heavier than the hardware in my last rig. While not as stout as some other rigs I looked at the added beef in the brackets cut down on the squeaks and rattles for the empty rig rolling down the road.
Vinyl floor in the main traffic areas
Heated tank areas with an arctic pack setup.
So what about things I've noticed that I really like of over the last few years:
External black tank flush
Outside shower for dog and kid cleanup
Garbage hole in the counter with external access to the trash can to change the bag. Keeps the mess under control and the dogs out of the can. I don't know if the bunkhouse has this option.
Foam and fabric in the bunk and dinette is holding up much better than our old unit (Thor).
Factory service center. It's in Indiana and I'm in North Carolina but for the big repairs I'll take a drive. I'll be posting about my experience with their service center soon
Rumor has it a dyson vacuum is an option for the rig. I have a compact model that we carry with us from the house and if I had an option to have one included on a new rig I would jump for it.
The drawers and cabinets are fairly typical fare but the luon and aluminum construction is a big plus in my book. I don't have to worry about delamination or mold in the walls.
Folks downplay the cedar lined drawers and cabinets but I can say that after two years my rig still smells new inside and that's after heavy usage by two teens, two parents, and 2 -3 large dogs. I'm sure the cedar is part of the reason for that.
The cushions are zippered and lined so when something is spilled you can take the cushion out and wash the covering. The coverings have held up well to washing as well. Getting the plastic wrap back in place and back into the covering is a bit of a trick though.
I like the fiberglass roof. It's less work to take care of than a rubber roof. Older units had an issue with leaks between the front roof and cap but that has been addressed in the new rigs.
