Personally, I feel Better Call Saul is better.
I wasn’t going to watch it because I kind of hated Breaking Bad by the end because everyone I liked was gone. I turned BCS on randomly one day, gave it a couple episodes and realized I liked it.
BCS basically continued off where BB left off in style, writing, and ideas, and just continues on. There is just more likable characters through the show too.
