If we inspect Dron parva, when Brahma was about to destroy universe, because he was angry with overpopulation, shiv pleaded him to spare his own creation.. we can see there's immense respect and reverence towards Brahma here.
"Rudra said, 'Be inclined to grace. O lord of the universe, cherish not the wrath for the destruction of creatures. No more let creatures, immobile and mobile, be destroyed. Through thy grace, O illustrious one, let the threefold universe, viz., the Future, the Past, and the Present exist.
Thou, O Lord, hadst blazed up with wrath. From that wrath of thine, a substance like fire sprang into existence, That fire is even now blasting rocks and trees and rivers, and all kinds of herbs and grass. Indeed, that fire is exterminating the immobile and the mobile universe.
The mobile and the immobile universe is being reduced to ashes. Be inclined to grace, O illustrious one! Do not give way to wrath. Even this is the boon I solicit, All created things, O divine Being, belonging to thee, are being destroyed.
Therefore, let thy wrath be appeased. Let it be annihilated in thy own self. Cast thy eye on thy creatures, inspired with the desire of doing them good. Do that by which creatures endued with life may not cease to be. Let not these creatures, with their productive powers weakened be exterminated.
O Creator of the worlds, thou hast appointed me their Protector, O Lord of the universe, let not the mobile and the immobile universe to be destroyed. Thou art inclined to grace, and it is for this that I say these words unto thee.'
Same is the case with Brahma for shiv too. He appealed to shiv to destroy The Tripura forts, which only shiv was capable of .
Brahman then offered his adorations, unto Sankara, and said these words for the benefit of the universe, 'Through thy favour, O Lord of all, the Lordship of all creatures is mine. Occupying that rank, I have given a great boon to the Danavas.
It behoveth none else, save thee, O Lord of the Past and the Future, to destroy those wicked wights that show no regard for any one. Thou O god, art the only person competent to slay the foes of these denizens of heaven that have sought thy protection and that solicit thee. O lord of all the gods, show favour to these.
Slay the Danavas, O wielder of the trident. O giver of honours, let the universe, through thy grace, obtain happiness. O Lord of all the worlds, thou art the one whose shelter should be sought. We all seek thy shelter.'
Brahma also respects all beings irrespective of their nature, Dev's, Asura, Yaksha gandharva or humans, and other beings.
And all the dwellers in heaven repairing thither behold the Supreme Deity when they please, and worshipping him with a bow of their head return whence they came.
And, O king of men, the Grandsire of all created beings, the Soul of the universe, the Self create Brahma of immeasurable intelligence and glory, equally kind unto all creatures, honoureth as they deserve, and gratifieth with sweet speech and gift of wealth and other enjoyable articles, the gods, the Daityas, the Nagas, the Brahmanas, the Yakshas, the Birds, the Kaleyas, the Gandharvas, the Apsaras, and all other exalted beings that came to him as his guests.
Brahma also treats other gods like Indra , Agni and Vishnu too with great reverence.
Fact is this doesn't necessarily create a hierarchy of honour. But reflects on the great nature of these gods.
