I feel you. In my high school the 4s were aspirational while the 3s were considered last year's boring, plane, pre-curser to the amazing 4. Once the 4s came out absolutely no one cared about the 3. That said, today it can be considered more wearable as it's far more subtle with less going on. And it doesn't yellow as badly b/c there's no mesh; though the back tab did. That made the black colorways so awesome. The midsole did, however, yellow on both models. I personally never took a second look at a 3 until the past decade; it was always 4s for me. Now I enjoy wearing both. And while 3s are still way more subtle and very wearable, I like the 4 more.
I agree about the 5. It was freak'n awesome. The clear sole with the jumpan on it was truly mind blowing, and the 3M tongue was unreal. The shark teeth were cool too. It was considered amazing like the 4 and even better at that time. The 6 design was so unique that it turned heads, but I wouldn't say it was overall preferred over the 4 and 5. Again, no one gave two s**ts about the 3 in my world at that time.
