But I find it quite interesting that 30Mbps is considered good for this router, considering there are many other routers out there that would allow me to get better speeds.
This is an assumption without any data. There are many limitations as to the throughput; using 2.4GHz provides for generally low bandwidth.
I look forward to your results, but can share some of mine. Basis - iperf with a Linux server on the other end; wired bandwidth through infrastructure is ~940Mbps with single stream TCP iperf, so full line rate:

I can't easily attach a screen capture of winbox to show the connection rates, but it is consistent with what the Mac reports. CPU usage is around 75%. This is a perfect test; I am close to the APs and the system is engineered to show maximum possible bandwidth. So it might be possible to get the rates you want, if everything falls your way... if you have little interference, if you have 2x2 clients, if you use prudent channel selection, if...
The results are obvious to me that 802.11ac is real and performance is superior. I use 2.4GHz for guests and legacy. Anything that really needs to the use network gets 5GHz. Not all 802.11ac is the same, it is unusual that I find an AP or wifi system that gives this good throughput - but it is possible.
