in terms of most stable, least bugs and fastest?
I'm not much of a believer in having the latest and greatest iOS, so if I can downgrade to a more stable iOS, I'd prefer that. My iPhone 8 came installed with iOS13.3.

You can't downgrade, so your original question is moot for you.
But even if you were on 12.x, I haven't noticed any performance degradation from 12 -> 13 on my iPhone 8.
