In the pub or on long train journeys the topic has often come up "which of these local rivals do you prefer (or dislike least)?" With some it's easy to choose: Everton not L'pool, Sunderland not Newcastle, Sheffield Wednesday (blue) not Sheff Utd. But between Arsenal and Spurs it's a lot harder. If you HAD to pick one, who'd it be? The arrogant Tarquins who've grown even more dislikeable under Arteta in the past year, or Tottingham going back to 1981?
More generally, do folk have preferences, however peculiar or irrational, between, say, Norwich & Ipswich? Southampton & Portsmouth? Derby County & Notts Forest? Swansea & Cardiff? I'm not getting into Scottish rivalries but further afield is it Roma or Lazio? Benfica or Sporting? River Plate or Boca?
