Superman probably respects Bateman significantly more than Batman respects Superman.
I would say the person he respects the most in DC is John Constantine. John is the one human who does things that Bruce knows he himself couldn't.
Honorable mention to Dick Grayson, but I'd say maximum respect would be to John. Or at least a form of awe. John is one character that (thoroughly) punches above his weight, even by Bruce's standards.
Lack of respect ...I would say Bruce harbors disrespect for most 'powers' characters. Not Superman, or the likes of Diana, because they often put themselves at real risk against beings that have greater powers than they do. But definitely disrespect for powers characters that could do more but don't. This can be seen in two ways - how he reacted to Gotham and Gotham Girl, initially having a lot of hope since he knew the city needed such characters, and then the disappointment and disdains when Gotham failed and allowed himself to be used against innocents.
The second is years back when Batman and Superman (and Big Barda and Mr Miracle ...and maybe Wonderwoman but I'm using memory) raided Apokolips to rescue Super Girl. Bruce got injured at one point, and Barda offered the use of a Mother Box to heal his injuries.
Bruce refused.
It was an interesting introspection of how Bruce looks at external powers, and probably means he has certain similarities with Lex Luthor on how they view powers characters. The two men (Bruce and Lex) are true Super Men (ubermensch), and like any super man they will look down on those who were gifted powers rather than earning them. Also note that Bruce has turned down a Sinestro ring after being chosen as the one able to instill great fear in this space sector. He refused.
The only exception are characters like Superman and his like who constantly find themselves in peril fighting against more powerful beings. Such characters are Kal, Diana, Booster Gold (as explained by another poster), Raven (constant struggle against deep darkness), etc.
But a Guy Gardner with a magic ring ...chump.
