Choose the 330 or 336 first by the machine you want to represent, then by the viewing angle and working pose. Their similar catalog footprints do not establish identical detailing or arm travel.
Inspect the side that faces the room
The 336’s documented boom-side joint makes close side views particularly relevant. Ask for that view of the item you will receive. For the 330, inspect the engine cover against the surrounding body. Neither isolated observation establishes a defect rate or a controlled finish-quality winner.
Plan around a shared reach limitation
Both published inspections describe limits to deep digging. If the display needs a bucket below the base surface, request that exact pose before choosing either. For a parked lineup, machine identity and the view of the body may matter more than a movement you will never use.
