'lieben' and 'auf etwas wegfahren' can both express that you like something very much. 'lieben' is normal and works in many situations, for example with food, music, hobbies, or people. 'Auf etwas wegfahren' is very colloquial and sounds more like spontaneous enthusiasm or being crazy about something. It fits better in casual conversations, not in formal texts. In practical terms: 'lieben' is the safe choice, while 'auf etwas wegfahren' sounds casual and emphasizes that someone is really excited about something.
