The sphere of superior benefits (3)

I believe the answer is:

orb

'the sphere' is the definition.
(orb is a kind of sphere)

'of superior benefits' is the wordplay.
'of' indicates a hidden word.
'ORB' is hidden in the letters of 'superior benefits'.

(Other definitions for orb that I've seen before include "Part of royal regalia" , "Sphere for a sovereign" , "Heavenly body" , "Item of insignia" , "Sphere - eye" .)

I've seen this clue in the Evening Standard.
