I own and have used The Nox, The Legend and The Dues 2. The Nox has been a workhorse it does everything very well. Although everybody knows it has problems with flooding, arm cuffs and coil ears. I have had the 600 for 4 years and not a single issue. It fires up every time ready to hunt without issues. The Legend, built like a tank, great headphones, great company, good target recovery especially after the beach update, very quiet at all my beaches. In my opinion, a little out of balance, in addition, I don't have the confidence that I am hitting all targets like I do with the Nox. It is a very good detector at a great price backed up by a customer service that is second to none. The Dues 2, for the price, the accessories really look and feel cheap, the headphones, the charging system, the telescopic stem, and the aerial antenna for the control box to the coil. But, in my opinion the performance is unbelievable. I use it at the beach (only around 20hrs) and it gets the job done. The weight at my age (66) makes it a game changer even at the price. I just hope it can hold up for the long run.
