The 2x8 GB 2133 MHz DDR4 kit will in general perform better. This is due to the way the RAM interfaces with the rest of the system.
You see, individual RAM sticks are 64-bit devices, but most modern CPUs support up to a 128-bit connection to the RAM. These "bits" essentially act as lanes on a road. If you have 4 lanes on a road going one way, then traffic is going to be able to move from one road to move in that direction faster with less blockage compared to a 2-lane road.
The MHz here is essentially like the speed limit on the road. So it is very practical to view this as a 4-lane highway with a speed limit of 65 MPH, and a 2-lane highway with a speed limit of 80 MPH. The cars may be able to move faster on the 2-lane road, but as only so many cars can be on the road at a time, it manages to move less traffic overall than the slower moving 4-lane highway.
Much in the same way, the 2x8 GB 2133 MHz (which works at 128-bit because there are two 64-bit sticks in use), it will transfer data faster than the 1x16 GB 2400 MHz kit.
