What playstyle is better to play: Stealthy or Aggressive?

An Agressive Stealthy style is best.

Aggressive players actively taunt the killer, even use OoO, and want to be chased the entire match. Ideally if the survivor is good enough to loop the killer the entire match this is ok. But this kind of skilled player is quite rare. There aren't many players who can loop a killer for an entire five minutes while his teammates finish all the gens.

Chances are you'll go down after a minute or so and your heroics end there.

Stealthy players on the other hand just tend not to be productive. They are too careful and "immersed" so they avoid danger and risk, and don't do much Gen work.

This is far from ideal, though it can be fun to play. But it usually results in poor performance.

The ideal style in my opinion is the stealthy Agressive. Player. Stealth when needed to avoid the killer, but smart enough to know when to play aggressive to get things done. This style uses game sense and perks to know when it's dangerous and stealth is needed, and when it's safe to run around and aggressively work on gens and other objectives like totems and saves. And when ######### hits the fan, knows how to aggressively loop and juke.

Note that you don't need stealth perks to be stealthy.

For my first 500 hours of DBD I was playing full stealth. I used all the stealth perks. But that experience taught me how to stealth.

These days I barely run stealth perks. I just run stupid crap for fun. And I can still stealth almost as good as I did when I was running full Iron Will, Urban Evasion and Spine Chill.

That said, it's hard to switch from stealth to aggressive. The reason being: when you go for stealth, you have to go all in. And when you go for looping, you also need to go all in.

For instance, if you try to stealth, that means staying still and trying to "pass" the killer without him noticing you. A looper upon spotting the killer will break into a dead sprint to keep distance; distance is crucial for a looper to loop the killer. A stealth player on the other hand will stay still and keep out of sight; sometimes right under the killer's nose. (This is why Urban Evasion is so important to stealth players). But if the killer sees you at this point, you're screwed since you don't have any distance between you and the killer. You will get hit.

So early on when you encounter the killer, you have to decide: are you going to stealth or loop? You can't do both at the same time. You can switch between both styles in between encounters with the killer, but you can't change halfway in.

Looping basically means you're going all in on distracting the opponent so your teammates can get work done.

Stealthing means you're going to avoid the killer altogether. You won't be wasting his time, he won't even know you're there. So either you will be the one doing gens and pass off the killer to another teammate, or you are by an objective and you keep working on it, when killer passes by he will kick the gen and look for you. In which case you need to keep hidden and waste his time searching while you avoid detection. Then go back to gen, lather, rinse repeat. It is possible to waste a killer's time a lot in this fashion while getting work done on the gen in little increments.

Both methods are effective but both are difficult to pull off in their own ways. Stealth is by far much harder to do because stealth has been nerfed extremely in the past couple of years, and requires a lot of proper anticipation and mindgaming. One mistake and it's over. Savvy killers know all the tricks and there's not much more you can do but hope they guess wrong.

For which? Survivor or Killer?

When you want to git gud very fast just play always aggressive. This will help you to learn what is possible and what not. Once you are very good at judging distanced, not panicking while injured etc then I would mixture stealth into it. However, stealth would be at 20% use at max imo. The only time you start stealthily a lot is against a ridiculously strong Nurse main and eventually against spirit.

Just don't fear the killer and you will get better and also automatically will find the best playstyle on most situations.

Which is actually good! Who wants to rank up, it's miserable up there in the red ranks.

Stealth is also good against Nurse.
