Works for derp-dish pizza, which isn't really pizza, anyway.
A flat plate of either steel or iron is great for real pizza, though.

Cast-iron skillet may work well for deep-dish (I like the above "derp-dish" reference because deep dish really isn't pizza, it's more of a casserole) but it won't work for real NY or Neopolitan pizza.
As said in the quoted post, a steel plate is the best for cooking a real, NY or Neopolitan style pizza. Neo requires some modifications to your oven to get it to insanely hot temps, but NY style can be done with most home ovens.
That being said, what has been discovered through the course of many people converting over to steel plates from stones for cooking pizzas is that steel transfers the heat just a tad on the fast side to get a proper top/bottom cook so it takes a bit more work to control bottom heat vs top heat.
I have a few thoughts on ways to fix this but they are all more expensive than steel & stone.
Heat Transfer Coefficients of some materials:
AL: ~250
Carbon Steel: 47
Cast-Iron: 55-60
Stainless Steel: 19
Most stone products are 2 to 8
As you can see stone is around 2-8, stone-like substances marketed as baking stones can be anywhere on the spectrum but are likely close to stone. If carbon steel plate is too high at 47, we need something that falls in the middle. What, on the above list falls in the middle? Stainless steel!!!! Stainless steel = $$$$ when you are talking about a big, thick sheet of it.
For now I have 1/2" A-36 hot-rolled steel that I'm happy with and I will continue using. I just can't preheat it to full temp before starting. My typical process is to heat the steel to 400 for at least 1 hour to ensure it's fully heated. Then I crank the over temp up to 525 or 550 (depends on what kind of pizza I'm making. At that point the "thermal inertia" of the steel keeps it down around 425 even though the over temp is well above that. Once the pizzas start flying in the oven it keeps the steel temp lower than the air temp and as long as the pizzas continue to hit the steel somewhat consistently I can keep the steel temp at my target range of 425-450. If I take a break I have to kick the oven back down so it doesn't overheat the steel.
It would be easier if I didn't have to do that and I've wondered if SS would fix that issue but it's too expensive for me to get some just to try it.
