I still maintain that Frontier TV looked better overall, but that is because their character models looked better and, as I've said before, even the fights felt less "cluttered" than they did in Delta. I fully acknowledge some quality issues regarding certain episodes, like episode eight, oy vey, and some really sketchy stuff in the middle of the season as well, or that they reused some action shots. I'd still take Frontier over Delta every day of the week in terms of aesthetics.
And of course Sheryl and Alto looked better than all of Walkure combined.
