Orx.
Why: It really depends if you are coin shooting or relic hunting to a certain extent. Overall, I prefer to have a display with any XP SETUP (Orx or Deus) not for target ID but because it gives you pinpoint ability, mineralization level, ground level, and iron probability displays. Those are key to knowing how to set up your detector for different environments and types of hunting.
The Deus lite setup functionally works but really is designed for people who already have the remote to enable easier coil programming and setup. Once you have the Deus setup with the right tones and settings based on mineralization you can get away with just the headset (unless you need the pinpoint feature) for a detecting session if need be (works especially well if you want to "create " a second basic backup detector for someone, just need the coil and headphones). But to have no remote at all, really makes the Deus lite very limited, almost crippled.
If recommending a way to go for someone else who is considering the Deus Lite vs. the Orx = I would always recommend the Orx as the better overall setup.
That being said, if you are specifically doing coin shooting in park or ball field settings where there is a lot of aluminum trash, full tones is the best audio setup and you can only get that with the Deus lite setup - so for a pure coin shooter, I might recommend the Deus Lite.
The full up Deus setup is ideal, though. I think it is somewhat overpriced these days considering the other detectors you can get for that amount of money, but it is my favorite detector. If you can get a good deal on a used controller, that is the best way to go.
