I love SG0 more than the original series, because it elevated the original even more. Also, I find the Sad Scientist a more compelling character.

The revived Mad Scientist is just as compelling
On another note, I liked Okabe x Kurisu on its own after I watched the OG, but SG0 made me like Okabe x Mayuri better.
I enjoyed it, but not more than the original. From what I remember, which is not as much as I thought, it became a bit of a slog for me either midway through or towards the end, which didn’t really have a pay off like the first eps of the original did.
