Like one better than another (6)
I believe the answer is:
prefer
'like one better than another' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for prefer that I've seen before include "Favour, like better" , "Value more highly" , "Choose over others" , "Choose as more desirable, like better" , "Tend to choose (one thing over another)" .)
