Is there even such a thing as analog sound in theaters these days?

I know there's still the big debate on whether celluloid or digital is the best way to film a motion picture but no one really talks about sound.

Back then, correct me if I'm wrong, when talkies were invented, all sound was mono, 1 channel. Disney tried to invent a new tech, which had 3 channels for surround but that was too impractical at the time, so films remained in mono. However, with cinescope emerging, it had its own sound format, which had 4 channels for it, thanks to its magnetic sound, which were better than the commonly used optical sound but, again, was impractical. Then came another film format: 70mm, where the sound had 6 channels for it. Dolby went and made their own format of sound reduction for 70mm, where they gave another channel to a subwoofer, creating analog 5.1. After that, stereo was invented, 2 channels, and that became the wildly used format.

And so digital sound was created, Batman Returns being the first to be released with it, 5.1 became more wildly used, and the rest is history, with Dolby and Datasat (DTS) competing to whether which one is better.

My questions are: is analog sound better than digital sound for films and are there any films that are mixed in analog rather than digital, and if so, can they be released in that format?
