If anyone is on the fence, painting these minis is a lot faster than Imperial Assault. You can just do base coats, drybrushing, and washes and make it look nice fast enough. For the storm troopers I just primed white, did a black wash and touched up a few black details on the mouth and eyes plus retouched some white.
I think the only thing that will be really tough to paint will be the Rebel Troopers.
