Is Metal better than Plastic for USB pendrives?

Planning to buy a 128GB USB 3.1 pendrive for storing stuff. Came across these two similar SanDisk pendrives at Flipkart. One is made with Plastic body while the other one is metal. AFAIK metal version is more Durable than plastic and has better heat dissipation but it's relatively expensive. If anybody is using a USB 3.1 or 3.2 pendrive made with metal or plastic,let me know about the performance, reliability,etc.
