I am not surprised that you know them well enough to be able to say that.
There's really a pretty big change between '95 and '96. They had slowly "enhanced" the hair detail since 1991 but then in '96 further enhancement was muted but they reversed the concavity of the coin. Where before the reverse was "concave" it '96 it became the obverse. It was '96 when people started complaining about "spaghetti hair". It just doesn't look right.
The states coins have a little better "balance".
Small changes in the design were coming faster and faster back before the states coins and rather than occurring every several years as in the past there were larger changes every year.
I still watch these '90's era coins hoping to find mules. These are coins struck with the wrong reverse die. In the modern era I believe these are made at the beginning of the year when the obverse die is swapped out for the new date and then they forget to change the reverse die. Unfortunately, reverse design changes were minor in this era so mules would be hard to spot if they exist.
The '96 is just an ugly date to me. The '97 and '98 are a little better but still "spaghetti" as are later quarters.
Time don't fly, it bounds and leaps.
