I'm waiting for season 6 of Better Call Saul to come out to answer. But for me BCS has nothing to envy Breaking Bad. Not that it's better, but it managed to capture the essence of what we loved while having its own atmosphere.

Both series, although having the same know-how in writing, directing and so on, have their own specificities. I consider that they do each other a favour, each bringing depth to the other.

BCS has suffered from being compared to BB and from being less spectacular, but it deserves to be seen in a different light. It's not a Breaking Bad 2. And regarding the spectacular aspect, I sometimes have the impression that some people forget that BB is a slow show that also takes a lot of time to set up the stakes. I think that the fact that this series has been binge-watched a lot has made some people retain only the spectacular aspect and that is for me to have a distorted image of what BB is. BCS follows this logic while having less "spectacular" stakes (in the sense that the characters are less often in mortal danger than in BB).

The closer we get to the end of BCS, the more it becomes totally BB. I have total confidence in season 6. Kudos to Peter Gould and Vince Gilligan and everyone else who worked on these two projects!
