Over reved alternator?

Sounds reasonable to me Dell with my zero understanding about anything inside these charging components. It wouldn't surprise me a bit about them all being made the same in one place.
May I ask this question another way? Do you prefer the old or newer style regulator/alternator system?
Say your car was to need a custom harness made up anyway and you had the choice to put in one system over the other. I have the tools and am capable of making a harness fine. I have rewired several of my cars and trucks from belden spools that worked right out of the gate but don't ask me what is inside of the regulator or alternator.
I'm thinking AJ got 15 years out of his, to me thats impressive & was curious which he was using.
On the old cars and trucks you could take the cover off and clean the contacts and adjust them if needed.
These parts with the gel poured into them baffle me.
I can't tell the good from bad.
