I remember liking some early DELUHI songs, but I feel as if they got worse as their career progressed. When everthing was said and done, they were one big hot mess. DELUHI may have had a more diverse discography, but you also have to keep in mind that DELUHI's career lasted about 3 years when GALEYD were only active for aprox. 1 year. I feel like GALEYD probably would have diversified eventually, but they were probably still getting used to writing songs together and developing their style. Who knows. But even still, out of the whole metalcore/power-metal-ish hybrid sound that the bands played (especially with the hard/heavy verses and poppy choruses), I feel like GALEYD executed it better than DELUHI (iirc, I remember cringing at how tacky some of the verse/chorus transitions in their songs were).
Vocally, I feel like Garo was just more solid all around than Juri, as he didn't suffer from a lot of the typical VK vocal inflections (which is a plus for me since so many VK vocals turn me away from the scene). Also, Juri has a slightly annoying vibrato.
WIth that said, I think both bands were talented and were welcome sights in a scene with such a dearth of quality musicianship. However, while I feel DELUHI were on a steep musical decline, I feel like GALEYD had a lot of potential to fulfill. So i'm rockin' with GALEYD in this one.
