Don't get me wrong I LOOOOOVE angry ronald but all of the others - hmmm that's pushing it - but yes, personally I believe he would be more than a match for Curze
My argument comes from the fact that Angron has been pretty much venerated/cosnidered the ultime fighter among the primarchs, which afterall makes sense since he was a gladiator ever since his childhood.
Both Lorgar and Argel tal in " Betraye
r " state that Angron is unmatched in combat, and Lorgar himself believes that no one could best enraged Sanguinis save for Horus and Angron himself. Couple that with Corax's praise and his feats of beating Leman and Guilliman, it's easy to see why Angron ranks in top three easily.
Where other primarchs are generals and lords first, Angron is a weapon in itself. Betrayer
explains how Angron was literally robbed of everything but his martial prowess.
Now im not saying Angron couldn't lose to other Primarchs in certain circumstances, since a battles' conditions certainly doesn't always goes in one's favour, but in a clear, fair one on one fight I don't see him losing to anyone, even Horus.
However, if you put Angron in a pure brute strength contest, I think no matter how much he got enraged, he prolly wouldn't best Vulkan.
Or if you landed Alpharius/Omegon/ or Corax and Angron in a jungle and told them to locate and eliminate each other. I think under those conditions Alpharius's/Omegon's resourcefullness and Corax's stealth would prevail over Angron's mindless drive to stop forward.
Curze is a dirty street fighter type, and once Angron starts to think he won and turned his back on him, he'd find his chest pierced by a pair of claws, but in a fair fight, Curze would get torn to shreds.
