Don't know any of them but I watched the videos of them both boxing.
I think Eddie would win. That Kyriakos guy seem to have no leg work at all, his upper body movements is lacking too (so I doubt he's any good at dodging, can't see him bob and weave), his guard is always down after a punch.
Eddie is a bit better, move his upper body, the leg work although not very good is still present.
They both have some power mainly due to their weight.
Overall those 2 guys are too massively big to be good at boxing but Eddie seems better.
