No wrong answer on these two excellent projectors, just depends on the user's goals and situations. Me, I am staying with regular blu-rays for the next few/several years (I don't stream), still enjoying my library of close to 2,200 discs (and still growing at great sale prices), so I wanted the very best JVC blacks and contrast to breathe life into my existing movie collection: that meant the RS540/790, and the fact my dealer gave me a killer price sealed the deal. The JVC is a huge upgrade visually, it's like watching all my movies for the first time with the reference grade blacks/contrast, stunning color, a sense of realism and depth, in another league compared to the Sony 45ES I'm coming from and the Epson 5050 I've been testing.
The current JVC native 4k units took a small but noticeabke step backwards with black levels and contrast according to respected reviewers and experienced forum members, and they still are not as bright as what I personally want when I do go 4K UHD on a 150" screen, so I am enjoying the killer 540/790 for the next five or so years, and then I will look into the latest JVC at that time when they have brought their famous contrast and black floor back to previous levels and have increased brightness more, or even switched to lasers below wealthy person pricing.
Others on the forum want native 4K UHD and better tone mapping *now* so for them NX series is sweet and they aren't bothered by the slightly worse blacks/contrast compared to the previous generation. They've made the best choice for *them*. No wrong answers here!
