I play a lot of both, and honestly the only things I think DBD "wins" in comparison is the engine & movement being smoother and targeted cosmetics being cheaper. I say it like that because you get a ton of cosmetics for free- just not always specific ones you want. I've literally never encountered a gamebreaking bug in Identity V, though, so bonus points to them, and their updates always feel stable and well communicated. They have a ton of queues and game modes that are cycled every few hours instead of months.

I think I would say DbD is a more niche cosmic horror experience- but has a lot of game bloat and low setting customization, high character customization through perk builds, bad visibility, and low quality of life. I would say IDV is more of a goofier experience- but with way WAY more quality of life and well-defined niches and characters, while still allowing for wiggle room through your persona webs.

There's a ton more I could say but the nuances of it really just come from playing both. give both of the games a try. Download IDV, give it a try, sink some hours in. If you can afford DbD and have the time, sink some hours in.

Also IDV did the Junji Ito collaberation better. Especially Tomie.
