>Better replayability
DBD, not even a question.
DBD
-10+ Killers each with unique powers and build potential due to the addons system
-25 maps
F13
-1 Killer with 9 statistical variations, no different abilities between them
-8 Maps.
>Better core gameplay loop
>Better balance
>Higher skill ceiling
Neither. Both games have abysmal balance and gameplay.
Logically a "1 Villian vs Many Humans" game would be balanced around having the "Villian" be "powerful, but alone" while the "Humans" are "weak but numerous".
However with DBD and F13 the "Humans" side is both the numerous role and the power rule.
The Villian player will always lose if the Human side player arent retarded and is playing the game properly.
Just an utter mess.
>Better style
Mixed.
F13 is a better looking game overall, but its very plain.
DBD on the other hand looks like ass graphics-wise but it has a lot of neat designs.
>Better spooks
Neither. In both games the Villian role is just a silly clown for competent human players to bully.
There is no spookiness or fear involved because the villain isnt a threat to any competent players.
On another note, while both dev teams are incompetent, F13's devs are outright malicious sjw cunts to their playerbase, organizing witchhunts against players they dont like and smearing their reputations.
TLDR: Both are shit, but F13 is far, far worse.
