Quad PDB vs Octo PDB

[h4344]

Is there any benefit to this Quad PDB which is rated for up to 20A per terminal for a quadcopter

Compared to this Octo PDB for the same Quadcopter but is only rated for 10A per terminal

I want to use 4 of these motors, im assuming the Quad is better suited because it is rated for more amperage but i thought i might get some input.
