A team that I consider a favourite today may perform poorly after a while or my favourite player may change. Also, since I have personal freedom, I can keep any club I want on my favourite list. If a team is good I will definitely support it. I'm also not in favour of supporting a team emotionally while people enjoy the game and are there for entertainment. I think my own preferences may change over time. No team should be emotionally supported for entertainment or betting purposes.
I think everyone has their own goals and reasons for supporting any team, because there are also true fans who continue to desperately support one team without wanting to support another team even though the team they support is no better than their own rival team. But for bettors and entertainment seekers it will certainly be very different from true fans who are generally very fanatical about one team even though the conditions are different from last season to this season.
