I like both of them but I've had a falling out with SU, not exactly sure but there's just not much pizzazz now. Thought homeworld would make things interesting but then they virtually remove 70% of the risk being in homeworld had with the universe in Lars and Lions hair (which makes sense that they took that route since they brought it up, it would've been irritating to watch Steven be willfully ignorant of such a thing for even the remainder of that episode, let alone more than that,) but 90+% of whatever bullshit Steven magic makes Lars nearly/more/as durable as Lion. Also I just really did not appreciate Smoky Quartz nor her extremely retarded, forgettable, and cringefully ham-fisted arc, along with all the constant crying.
SU isn't a bad show by any standards but it makes me say, "Really? You did that again?" so very often. Star isn't perfect either, the animation quality alone in season 1 really put me off from wanting to watch it (for the rest of that day, at least.) One episode was just absolutely abhorrently lazy and filled to the brim with errors. Fortunately it's been given a lot more love recently and I've always enjoyed the character interactions, something that's refreshing that's found in DXD shows, at least from my POV. Might be kind of LOL RANDUMB but the tumblr humor found in SU is a pretty tired schtick. Not /pol/, it's just the toned-down gay space rock shenanigans have been exhausted for me.
One may be better than the other objectively, dunno it's pretty late and I'm tired, but one is fresh while the other one has gone through so many god damn episodes. I haven't even kept up since Lars got resurrected/SDCC, have there even been any new episodes?
