That’s hard to choose.

Tomarry:

• We have so many Horcruxes to choose from. Or even Time-Travel if we want the original before he went bat shit insane.
• He has that aristocratic air about him that it sexy.
• Possessive and Obsessive to the extreme.
• Capable of so much.

Harrymort:

• Voldemort’s snake appearance is hot imo.
• He retains that possessive and obsessive thing which I like. For his character though. irl is not okay but him being a hot mess in fiction is great!
• Drama queen who loves to hear his own voice. Very human despite him trying to shed that likeness.
• His obsession with Harry specifically is interesting.
• There is a bond between he and Harry thanks to the Horcrux. I like using that in fics.

Thankfully HP has so much in terms of world-building so there are so many avenues available to us plot-wise for fanfiction. If you are a decent enough writer you can make anything believable. I’ve got people who didn’t understand the ships, reading my fics just because I wrote them, and coming away interested in the ships and asking for recs.

I think I like them equally because there are differences but at the same time all of the possibilities can apply.
