I have both Artizan/Crusader FJ's and those from May '40, and they're both great.
I love the Artizan ones (they were my first) because they're really easy to paint and they're sturdy. This is especially visible on their weapons, which appear quite stubby and thick, compared to the May '40 minis.
Those are especially awesome, but their weapons move a lot towards the realistically proportioned, meaning that the rifles are both thinner and longer compared to the Artizan offerings.
I bought them to work well with my May '40 Dutch, but since I already had a bunch of the Artizans, I'm still on the fence whether I will mix them or not...
