niftier

'more pleasing' is the definition.
Both the definition and answer are comparative adjectives. Perhaps they are linked in a way I don't understand?

'nodding head if row' is the wordplay.
'head' suggests taking the first letters.
'row' becomes 'tier' (a tier is a row of things).
The first letter of 'nodding' is 'n'.
'n'+'if'+'tier'='NIFTIER'

'is' acts as a link.
