What did you base this ranking off of? Not trying to be a dick, but actually curious. I know there are some aftermarket flow forming processes that are pretty well documented, the same with forging, but there is very little info I can find on OEM wheel manufacturing.
The only thing I will say that makes OEM wheels "better" is the amount of ridiculous testing they HAVE to do in order to get them to get the OK for use by the NHTSA.
That said, even among different wheel manufacturers it's not fair to say which is "better" most of the time.
Example in terms of "you get what you pay for" is any Ray's/Volk wheels. They set standards two to three times more stringent than what the NHTSA/TüV require to pass OEM tests. Their Spec2 rating pretty much rates a wheel to be safe to be driven on after a tire failure at low speeds to gtfo the way of race traffic.
Then there is HRE wheels. Most of their offerings are forged, very nice looking, and with a price to match Ray's/Volk. I am not saying by any stretch that they're not strong wheels, but they don't test strength and surpass safety standards like Ray's does.
Same with OZ, who like Ray's/Volk, actually make a lot of the wheels you see on actual race cars in a lot of different series.
Remember though, just because something is expensive, doesn't mean it's super strong. Same with "just because it's cast it's weak".
Enkei RPF1s are cast, and probably one of the, if not the most popular wheel used in the track day enthusiast demographic. Why? They're reasonably priced, super light, come in almost any size, and they're strong. Enkei is an OEM manufacturer too.
The stock Austins are a prime example of an OEM cast wheel that IMO/IME suck. They weigh a ton and are very prone to bending. I've never dealt with a bent wheel from hitting a pot hole before until doing it on the wife's car, so overall YMMV.
Personally, for aftermarket, I'll stick to manufacturers who make wheels for racing. I have a set of Volks for myself which are forged, and the wife has a set of OZ's which are pressure-cast. I've owned/tracked OZ's in the past and had them x-rayed after seasons of abuse with zero issue and tons of hard miles. There's nothing wrong with a cast wheel if it's made by a company that does their homework.
If you want the strongest lightest wheel you can get, it's most likely going to be a forged wheel.
