I saw it broken down like this and it's perfect description.
Breaking Bad is a plot driven show with excellent characters, and Better Call Saul is a character driven show with an excellent plot.
I'm actually enjoying Saul more. I don't know if I'd say it's a better show or not. I don't think it's as ground breaking or innovative maybe, but fukk...the whole creative team has just mastered their craft. The cinematography is absolutely out of this world, and they're able to really indulge themselves in taking their time with telling a slow burn story and connecting things. Odenkirk, Rhea, and Mando all give powerhouse performances too. I find Jimmy and Nacho to be more relatable than Walt and Jeese as well, for whatever reason.
I'll probably never say it's better than Breaking Bad, but I enjoy seasons 4 and 5 of BCS as much as any season of BrBa. I do think the slower seasons on BCS are maybe a little sower than the slower seasons on BrBa.
BCS is a very nuanced show, and I absolutely love it. Somehow both shows really make each other better. Some people might say it's better if they really nail the ending, and no matter what I think, I probably wouldn't argue with them.
It's a close call IMO.
