Martial Universe vs. The Great Ruler – Which is Better? (Donghua adaptation)

After watching Battle Through the Heavens, I got curious about the other connected stories like Martial Universe and The Great Ruler. I ended up watching The Great Ruler first (not sure why, since Martial Universe comes before it), and I actually really liked it! I finished it yesterday and found out that it’s only Season 1 with no news of a Season 2 yet, which is a bit disappointing. I enjoyed TGR because it focuses on just one female lead this time. That said, I still love BTTH despite its harem elements because I think the donghua handled it well.

I noticed Martial Universe has a lot of episodes, which is a plus for me. But before I dive in, I wanted to ask: Is Martial Universe better than The Great Ruler in terms of donghua adaptation? How does it handle the harem aspect compared to BTTH and TGR? Is the animation quality on par with BTTH and TGR?
