Minipc standalone ethercat vs Minipc and mesa card ?

Hello, I have been doing some research and I want to understand better the difference on these systems, for instance these setups in the videos use Raspberry pi 4 and Ethercat so he can directly talk to the servos and no mesa card is needed, I understand Ethercat makes wiring much more simple and the cabinet has less parts,also on some servos is possible to do homing directly, some cons seem that is  harder to implement because there is less info out there and hardware is possibly more expensive usually, but my question is to know if it is as powerful as a mesa card setup on the max step rate side of things? any other toughts I may be missing?

 


Thanks!
