You already know their teams and/or what type they'll use.
It's also just an excuse to recycle shit instead of making new characters.
The Elite 4 was hype because you would be facing literally the strongest people in the region, not some commoner you already defeated.
They also mostly have some intimidating and mature aura to them, showing that they aren't just a regular guy. I know this is a Let's Go pic and Lance looks like a retard, but the other show pretty well what I mean.
