。
I much prefer working at night.
Literal
Night [at-に] work [obj-を] do-[direction-方] [subj-が] far likable [assertion-よ].
~方がずっと好き ('prefer X much more') — ずっと here is adverbial 'by far, much more.' The pattern [A する方が] [B より] 好き is the comparative preference form. The よ at the end makes the statement personal and emphatic.
