An existing rack changes the answer
Ares is an attachment purchase. Its strongest case is a gym where the compatible rack is already paid for and working well. The Australian six-post listing at Gym and Fitness is for PR-5000; REP’s broader US compatibility information does not make that package fit a PR-4000. Buying the correct series is the first condition of this recommendation.
The cable layouts reward different priorities
Both systems use 2:1 adjustable handles. Rogue’s separate lat and low-row outlets combine the stacks internally, avoiding cable reconnection when moving between those stations. That is a concrete reason to choose FM-6 for a room built around frequent pulldowns, rows and adjustable cable work.

Where the money should go
For a new REP build, add the frame, J-cups, safeties and required crossmembers before judging the Ares price. Gym and Fitness supplies the Australian Ares route; Rogue Australia lists FM-6 Twin. Those are useful starting points for two complete local quotes, with delivery and installation shown separately.
Specify only the options your room and training need. FM-6 plate storage increases width from 58.7 to 75.625 inches, and floor anchoring is required. A larger stack or deeper rack deserves its cost when it solves a known limit. Handles, a usable bench position and the right thigh support come before unused capacity.
