Comparing Rise of Kylo Ren vs the Legacy of Vader: Reign of Kylo Ren series?
It might be weird to compare them because they're linked together and part of the same comic trilogy. But then again the fandom compares movies within the film trilogies all the time so why not.
I don't think it would be a hot take to say that imo Reign was an overall stronger story arc than Rise. Part of is that it's just entertaining to read about the 'Adventures of Kylo Ren,' like a weekly tv show adapted into comic form, and it fills some of the gap between TLJ and TROS.
Another part of it though is that imo Rise of Kylo Ren felt rushed at only 4 issues. It tried to do so much - Luke and Ben flashbacks, Snoke and Ben's relationship, Ben and his Jedi friends, the temple destruction, establishing who are the Knights of Ren. And the core plots of Ben proving himself to Ren, Jedi revenge, and Ben's fall to the dark side. Soule could only spend a limited time exploring each of these things because they're all crammed into four issues. It's too short for the ground that it's trying to cover.
But Rise of Kylo Ren is still good and I view it as an essential prelude to Reign. Hopefully with Fall of Kylo Ren, 5 issues is enough for Soule to tell his story while also exploring the Dyad, Palpatine's return, and the other stuff that precedes TROS' opening.
