I haven't seen every show myself, and I'm generally against saying something is the absolute "best", but I'm extremely tempted to say Mebius here.

It was a show that really understood the "heart" of Ultraman, and was clearly made with a lot of love and respect for the franchise, all while telling its own interesting stories with a really likable cast and quality fight scenes. Episodes like the one with 80 or the one where they go into Mirai's backstory stand out as completely amazing, and even beyond the individual plots there were solidly paced overarching plots and a strong sense of continuity that kept the show from feeling stagnant. It didn't just forget things happened as soon as the episode was over.

Basically I have nothing I'd even begin to complain about with Mebius, and that's a good sign for it.
