Would there be a reason to cast a higher level version of a spell if there is no difference between it and it’s lower level version?

For instance:

Speak With Animals II seems to be the same as Speak With Animals I. There are other examples with other spells, but is there a reason to cast the different versions? Cost seems the same, effect seems the same…

    The Player’s Handbook says this:

    When a spellcaster casts a spell using a slot that is of a higher level than the spell, the spell assumes the higher level for that casting.

    Counterspell’s description says nothing to override this.
