I don't think a dynamic mic is better in this case. I disagree. I come from the metal
world. You don't want the dynamic mic for vocals in a metalcore style thing in
the studio. Typically there isn't a huge difference in the type of mic's that are used for screaming and a pop singer. I think people have this idea that it needs to be different because they usually can't actually scream, so they hear it recorded (Which is different than band practice where cymbals are being hit hard and the singer is low in the mix) and they think something is wrong. Nothing is wrong, the person just can't actually do the screaming they think they can.
For the screamers who aren't loud in volume but make their throat do the screaming "sound" they too still record with the typical condenser microphone anyone else would. The only difference in those guys, is you record them at -12 instead of getting any lower than that. You have to usually add gain from some source to make it appear as if the volume is loud. Even at -12 you can add a lot of gain to low volume screamers and it will sound good. I usually would compress the vocals and then bring up the gain the compressor and then I might use something like an ad limiter which allows you to crank the gain without the levels changing. Ad limiter has the limiter, so you set it at -12 for example, put as much gain as you want and it's still at -12. It also allows you to change the input signal to appear to be hotter sounding. But you have to be careful and don't over do it.
It takes practice to get it to sound nice and clear like a good metalcore recording. But a WHOLE lot of it has to do with most metalcore singers can't actually scream, they think they can. And they can't keep the monotone scream note going and their voice cuts in and out non stop and you can't really fix that.
Some of them TRY to fix that by thinking if they hold a dynamic microphone with their hands capped around the end of it they will scream into their hand and that will help it. That trick works live, But it sounds like CRAP recording like that. Because it isn't clear and the melody becomes much harder to hear for the listener.
I can tell the bands who record like that easily. And there are
professional popular metalcore bands who do that, but the good ones with good singers do not do that. They scream it right in front of the pop blocker like anyone else.
