The verdict
Both fit the same rooms on most dimensions — the deciding factors are setback distance, the data you want, and whether you'll pay for the software to unlock it. Run your exact room through the fit checker, then check current prices and subscription terms before you buy.
Space figures are planning estimates from published manufacturer setup guidance, not a guarantee. Confirm against each unit's manual and rehearse a slow swing with your longest club in the actual room before buying.
