Me Person; Good starter except that is a lot of jacks.
Darrius is an interesting war jack, I have not built him yet but have played against him several times. His cannon is effective at hurting infantry and some light jacks. His half jacks take getting used to.
The centurians are good and I like them as hard hitters, may have to get a second one for my force. The iron clad is a good battering ram and can take it and dish it out as well.
Good luck with your Cygnar force.
