1.) Cycle 1- The first cycle was by far the best. Awesome contestants who actually looked like models, great photoshoots, Paris!. The show wasn't hugely popular, so they didn't do all the cheesy commercial stuff they focus on now. Oh, and Elyse + Adrienne, of course
2.) Cycle 2- Not as good as the original, but still great. ANTM started getting pretty big for this cycle, so the style of the show seemed to change, but thankfully, only mildly. Once again, good selection of girls.
After that, I don't really care. The show's quality dropped considerably, and it became drama-focused and annoying a lot of the time. I keep hoping the next cycle will go back to the original style, but I doubt that will happen now
