Best in print, stylish (8)
I believe the answer is:
outsmart
'best' is the definition.
(outsmarting is a kind of besting)
'in print stylish' is the wordplay.
'in print' becomes 'out' (as in a book that is out).
'stylish' becomes 'smart' (similar in meaning).
'out'+'smart'='OUTSMART'
(Other definitions for outsmart that I've seen before include "Fool" , "Excel in cleverness" , "Fox; deceive" , "Outwit" , "Defeat by more skilful manoeuvring" .)
