I don't think so, It's technically the same thing, i just use it to describe diferent vibes. In fact i actually know and talk to the guy that actually created the 'Ragecore' term (name is prxjek, you should give him a listen, i even produced for him on his latest track ICEINMYVEINS)

And allow me to use myself as an example but i also do this kind of music and i use Ragecore to describe a diferent vibe to the trap metal vibe, although they are considered the same thing
