Comparing 2 standards across 12 specifications. 12 key differences identified.

Comparing:
ARRI Rosettes & Pins
Manfrotto 501PL

The ARRI Rosette (31.8 mm diameter with 60 radial teeth and an M6 central thread) and ARRI 3/8"-16 Anti-Twist Locating Pins (dual 3.0 mm indexing holes flanking a 3/8"-16 screw) are the de facto cinema rigging standards developed by Arnold & Richter Cine Technik (ARRI) to prevent camera cage accessories from twisting under heavy rotational torque.

The Manfrotto 501PL Video Plate (and its wide 504PL sibling) is the international standard sliding quick-release plate for professional video fluid heads (Manfrotto 502, 504X, Nitrotech, Benro, Sachtler Ace, DJI RS2/RS3/RS4 gimbals). Measuring 50.0 mm wide with a long sliding travel channel, it allows precise center-of-gravity balancing for cinema rigs.
