Benefit to using 20amp Python Helix power cable for MPC12a vs 15amp?

I am using the 12 outlets on the Shunyata MPC12a for my whole system including 2 Pass Labs 250.5 power amps.

I am also using all 12 outlets. Would a 20amp Python Helix power cable be of consequential benefit vs the 15amp?

Should I be looking at an Anaconda instead?

The wall outlet is a normal 20amp household circuit, I believe.

Thanks for the assist.
