Car Haul Trailer, Steel vs Aluminum, Which Would You Choose?

having raised, trained, shown quarter horses since I was a kid, had my first truck and trailer at 16, I admit I love talking trucks and trailers. kind of like us arguing bloodlines!
just info, regarding the gooseneck and 1/2ton trucks, realize the total weight of the trailer AND the placement of trailer axles has a big bearing on the weight applied to the pickup, yes mostly on the rear of course. I understand the guy going down the road 30 mi to the local track is different from making a rip 4 states away.
