Which of these two machines is faster and how do they compare?

For clarity, I mentioned some dimensional differences of the devices, but I didn't make it clear which dimensions they were different in. 250mm in the x axis is more useful than 250 in the z axis.

The dimensions of these two printers are:
(X x Y x Z)
250mm x 210mm x 220 mm (Prusa MK4)
235mm x 235mm x 250 mm (AnkerMake M5)
