The importance of living life to the full.
The importance of living life to the fullest.
Do these sentences mean the same thing? Is “full” or “fullest” more appropriate in this contest?
To the full is a saying meaning:
To the greatest possible extent:
enjoy your free trip to Europe to the full (ODO)
Fully; completely; taking the greatest advantage of the situation.

The expression is also used also with the superlative “fullest”, see Ngram and the meaning is the same.
