I liked it more than I thought I would, but the "AI fake" effect was a bit noticeable here and there. After watching the 4k UHD, I put in my Blu-ray from 10 years ago or whatever, sort of thinking I was going to prefer it's "less digital" graininess, but nope. Definitely found it more distracting than I'd remembered.
So of the two, I'd take the new AI version, though it's not perfect. But the happy medium might be the new AI release on regular Bluray. The lower 1080p image toned down the fakeness a bit I thought.
This is how I feel about it as well. It's not perfect, but it is the best, prettiest version of Aliens, hands down. James Cameron is notoriously picky about the quality of the re-releases of his films and I honestly think this was the best outcome here. Yes, a "grindhouse" style 4K HDR transfer of the original film negative would also be nice in order to get that classic film grain for those who are in the mood for it, but as it is, the release we got was exceptionally high quality even with its imperfections.
