Wiring up a new Fermenter Controller - wiring question to output jacks

[rkhanso]

I'm setting up a new Fermentrack controller. I have 3 standard US pattern jacks (panel mount) that I need to wire up. One for the Heat-Tape on the fermenter, one for the pump to run glycol/water for cooling, and one to run the window AC unit to chill the glycol/water tank.

I'm using a standard 10A Arduino type relay for the heat and the pump and a 40A SSR to run the window AC unit.

When I connect the wires up to the panel-type outlets, should I be using spade connectors? Or would it be acceptable to just solder the wires onto the terminals?
Here is a picture of one of the 3 outlets I'm using:

Either spade connectors or solder is acceptable. Separable connectors make maintenance/upgrade easier.
