Who should buy which
Home and studio buyers who want the full ARX exercise list, grips and attachments on one machine, with per-rep force data. ARX names founders building a studio around one machine, clinics that need movement-specific loading, and home-gym owners replacing a room of equipment.
You enjoy free weights and have the hours for them, you do not want a single-purpose $46,000 machine with a $200 a month software bill, or you cannot give it a dedicated 20A (110V) or 15A (220V) non-GFCI circuit and 37 square feet.
Home buyers who want ARX's motor-matched resistance and per-rep force data in the smallest footprint ARX makes, and who will use six guided movements rather than a full cable library. ARX names studios running clients back-to-back, athletes in season and busy professionals.
You want the Omni's wider exercise list, grips and attachments, you cannot give the machine a dedicated 20A (110V) or 15A (220V) non-GFCI circuit, or you are not ready for $43,000 in hardware plus $200 a month in software on top.
