It's been so long ago, I can't remember whether it was an exciting fight or not.
Superman is SO vastly superior to Batman I don't get how it would be even close.
True, and Batman has to use Kryptonite.
I'm no comics scholar, but that's how it went in the Frank Miller "Dark Knight Returns" comics popular when I was in college. Bruce Wayne teamed up with Oliver "Green Arrow" Queen, both armed with kryptonite gadgetry, arrows, etc. to fight Superman to a draw, or better.
You'd think Superman would at least DETECT the kryptonite and decide to back off and use heat vision, cold breath, etc.
