2023 XSE 25th Anniversary Windshield

I have a 25th Anniversary Sienna and have had a rock hit my windshield on two separate occasions. First one got patched by safelite but looks like garbage. Second one I have not had patched yet.

I’ve been looking for a replacement. The shop my dealer recommended has a replacement for around $550, and a Toyota OEM one was almost $1000.

Is there a big difference between aftermarket and OEM? Also, is there any way to source an OEM windshield cheaper?
