I have swapped for an AX210 and it works great. It’s definitely a more consistent performer (as in no weird ping spikes), but has weaker bluetooth. Overall the difference wasn’t as big as I heard about.
I have tried a few wifi cards recently and based on my experience:
RTL8852 < MT7922 ≈ AX200 < AX210
I ended up rating the AX200 and MT7922 about the same at my home setup as the MT7922 has significantly superior bluetooth, gets better throughput on strong signals, same throughput on weak signals, but has a weird stuttering issue where ping times suddenly goes really high for about 5 seconds every now and then.
The RTL8852 is absolutely terrible. It has at-best half the throughput of any other card at the same location (more often about a quarter), have incredibly inconsistent ping times, high packet loss, randomly drops, and even have terrible bluetooth performance. Anything is a notable upgrade over that.
It came with my son’s HP laptop, and we put in the MT7922 I got from my FW16 and the difference was immediately noticeable.
OS: All systems running Fedora Linux. YMMV
