I'm curious about the opinions on 70mm (non-IMAX) vs Digital IMAX.
What do you prefer if you have tried both. Because those are the only mostly accessible options around the world.
Sound is also something to consider, because depending on the Theater they might have wildy different sound setups even different audio standards.
I've seen non-IMAX 70mm referred to 5/70 because the image uses five perforations per frame; IMAX 70mm is then 15/70 because it uses fifteen perforations.
Digital IMAX is much bigger:

Tried both, 70mm (65mm is video, 5mm is audio) is just superior in every way. There's nothing out there that compares, digital projections are still far behind.
For me, sound is more impactful than screen resolution or aspect ratio. Subwoofer arrays powerful enough for the audience to feel sub-bass are expensive, large, and need to be placed precisely in the room. I don’t think I’ve ever been in a movie theater that had acoustics rivaling a top-tier music venue or concert hall.
