Here's more clear way to think of that human notion of people being 'better' or 'less than', to help us correct that wrong, Phil 2:3, and it helps for me to see multiple translations for this one:
New International Version
Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves,
English Standard Version
Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves.
Berean Study Bible
Do nothing out of selfish ambition or empty pride, but in humility consider others more important than yourselves.
Berean Literal Bible
nothing according to self-interest or according to vain conceit, but in humility be esteeming one another surpassing themselves,
New American Standard Bible
Do nothing from selfishness or empty conceit, but with humility of mind regard one another as more important than yourselves;
King James Bible
Let nothing
be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves.
And, the context verses help in this:
1 Therefore if you have any encouragement from being united with Christ, if any comfort from his love, if any common sharing in the Spirit, if any tenderness and compassion,
2 then make my joy complete by being like-minded, having the same love, being one in spirit and of one mind.
3 Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves,
4 not looking to your own interests but each of you to the interests of the others.
5 In your relationships with one another, have the same mindset as Christ Jesus:
6 Who, being in very nature God,
did not consider equality with God something to be used to his own advantage;
7 rather, he made himself nothing
by taking the very nature of a servant,
being made in human likeness.
And being found in appearance as a man,
he humbled himself
by becoming
obedient to death—
even death on a cross!
