Aurora R15, upgrading Wi-Fi from Intel to Killer?

The difference between the Killer wireless network card and the original Intel wireless network card is the focus of debate among many users. After intel acquired killer and merged the killer driver, there were more disputes. Killer AX1675 is actually Intel AX210.
Killer AX1650x=Intel AX200 (M.2 2230)

Killer AX1650w=Intel AX200 (M.2 1216)

Killer AX1650i=Intel AX201 (M.2 2230 cnvio)

Killer AX1650s=Intel AX201 (M.2 1216 cnvio)

Killer AX1675x=Intel AX210 (M.2 2230)

Killer AX1675w=Intel AX210 (M.2 1216)

From Intel's ark database, the difference between Killer AX1675 and Intel AX210 wireless network cards is very small. Both are 2R2T specifications and have Bluetooth 5.2. Support WiFi 6E protocol (support 160MHz), the only difference is that Intel ax210 supports vPro technology, while Killer AX1675x does not.

overall experience: the optimization of the killer driver for Intel wireless network cards is excellent as always. The throughput and latency of the wireless network card are excellent. With Prioritization Engine traffic distribution, Intelligence Engine intelligent network optimization, Double shot dual-network load balancing and other functions, compared with the original Intel driver, it can give players a better experience

In a way there is no use of paying 20.00 more as its just the same but the added word of Killer?

In all honesty the difference is the Killer version comes with software. In my opinion, the software causes more issues than it is trying to solve.

With the current high bandwidth internet connections available to most users, I see little point in the killer software as it only works at local level, and not at LAN level.

If you think you need something like QOS or traffic priority, it makes a lot more sense to use a router with that functionality than using it at a local computer level.

paying extra for the killer software. The Intel® Killer™ Intelligence Center interface is packed with valuable features for gamer and creator PC users. It adds the ability to analyze, optimize, and control your PC’s networking performance.

Yes, but only for your PC. If you have a LAN with 7 other networked devices they will not be "optimized".

And your ISP provided router/modem combo might or might not support the QOS features from the Killer packets being send to it.

In the end it's better to either enable QOS features at the router level, or much better is to enable traffic shaping if supported by your router.
