I like 3, 2, 1, in that order.
I think 2, 3 would be best for a patch, 1 would be best for a t-shirt, although I'd make the orange on the handle and stars black, and make the remaining color on the stars and the lettering in the shield gold. It would reduce the number of colors and cost.
IMO, patches should be colorful and detailed as much as possible as they don't see as much wear and tear as t-shirts and will last longer, so paying for them isn't a big deal.
Also IMO, the 4 th pic would be cheap for a t-shirt, but it kinda screams "another ho-hum cheap t-shirt" to me.
