I don't want to talk to generally, as many competitors are great! Some will disagree but I do feel its devolving. We don't see the mass monsters like we used to see, especially with that super crisp condition, where the skin tightly wraps around like seren wrap. I also notice a lot of guys don't have deep separation that we used to see. This is why guys like Samson, Rafa Brandao, Derek Lundsford, Hadi and a handful of a few others stick out to me because they come in pretty damn detailed!
Also years ago one of my first mentors, Fakhri, made a statement saying with gear quality going down, so will the physiques. From working with so many people throughout the years, seeing what's out there, how people respond etc, I absolutely agree with this statement. High quality supplements just produce a CERTAIN LOOK! You also don't need to run as high dosages. I also am hearing and seeing GH dosages going way way to high, coupled with insulin which is just making some physique round and balloon like.
Aside from all that, we don't see as much "hardcore" training, dieting, cardio. A lot of things have been cushioned and made softer throughout the years. The effort in the gym, shows in the physique not only with size, but also conditioning. This is all just my opinion of course.
