Ran equinox 800's from the day they were available, for like 3 years, then a manticore this past summer's water season, with some occasional park hunts. Without a doubt you'd be gaining more ability to call more targets (with the broader vdi scale) and it'll call more junk targets junk (rather than throwing a good tone). It's slightly deeper with deeper vdi accuracy (usually), and occasionally you can see like a silver coin amongst adjacent iron on the trace screen (not always, not often, but I have seen and recovered a couple mercs and a couple indians that were next to iron with a perfect little round trace dot sounding off along with the rusty iron crazy trace). Would likely never have dug them with nox or legends and I may very well have missed them with either prior (same spots hunted hard). That ability may make it a worthwhile upgrade, as silvers in parks here are few and far between any more, so being able to go with a goal to seek/find the rare or ultra masked coins was nice. Having said that, I sold it and got a deus 2 again and have had success finding deep/missed/masked coins in the same spots I had been pounding with every prior detector.
