Personally, I found the voting far more subjective than the reccing, because while I at least knew which fics I loved personally enough to call favorites and therefore rec, assigning values to numbers is much harder. Not to mention, everyone's way of voting is different.
And while I tend to lean towards Epilogue, Canon IMO also had a strong showing. However there are shippers who don't read Epilogue fics and others who did not like certain Canon!fics for the lack of a happy shipper ending. There were also peeps who just adored the EWE and Fanon entries. Ultimately though I guess the tiny point gap shows it wasn't so much about anything other than the H/D lovin'.
The thing about the hd_worldcup that I adored was the generally fabulous fic. The competition aspect led to a lot more good reads than I typically expect from a fest. I'll always look back on the fest's posting period of shiny fanworks with fond memories ♥
