She definitely deserves some attention. The 727 was the plane that infected me with that CS steam gauge plane virus. The 707 then blew my mind on the optical qualities and the feeling and I have high hopes for the 737 too.
The bug list on the 727 is long and she sort of needs some tweaks, so if 2.5 would sum up some of the things and render them issues of the past, my heart would beat with even more passion for her.
