Choose between these models by the role of the front blade and the intended cab scene. Both are 1:50 excavators, but their distinct machine identities and miniature movement limits matter more than a generic brand ranking.
Make the front blade earn its place
The 335F adds a front-blade element to the composition. If it will be hidden behind the tracks or another model, that distinction may contribute little to the finished display. The 320 GC supplies a more conventional excavator subject without making the blade the visual focal point.
Treat transport and trench poses as separate questions
The 335F inspection reports incomplete folding as well as limited lowering. That is relevant to a transport scene even if digging depth does not matter. The 320 GC also does not reproduce every full-size movement. Test the pose needed for your layout rather than choosing whichever description lists more moving parts.
