If you mostly care about VPN speed: Comparative Throughput Testing Including NAT, SQM, WireGuard, and OpenVPN
The wireless on the WRT3200ACM is questionable. Mainly because there are several bugs (including one that prevents WPA3 from working) that are unfixed as a result of Marvell being bought out.
For wireless performance, the best router I've personally used is the R7800. But that has questionable wired performance.
No silver bullet here.
