Flashing the R7800 is trivial. Not sure why you think otherwise. I have no experience with the Linksys so I cannot comment. I did find this thread on a quick search (although some of the info therein is likely dated given the age).
Thank you for the suggested link. I'm taking a look and reading about some latency issues, I'll go into it.
As for the flashing procedure, I found the guide on the official device page on OpenWRT https://openwrt.org/toh/netgear/r7800 and I understand that I must use TFTP, but maybe I'm wrong. You have it, can you explain the procedure from scratch and tell me about disk space and performance? I am very keen to buy it, if I remove some doubts.

I remember using atftp when I went from 17.04.5-->18.06.1 due to some differences in image sizes as I recall. Subsequent updates have worked just using the LuCI interface.

Disk space problems? Stability? It now costs very little. I think I buy it.
What are you talking about??
I ask you if there is enough disk space for OpenWRT in normal use and how the WiFi is doing, if it is stable and performing.

I agree with @moeller0 there really isn't an all in one that's entirely suited to keep up with 1Gb ISP. Consider a main router running strictly wired, and one or more APs for wifi. Ideally the main router would be an x86, but you can keep using your 3200 there and have generally enough CPU.

I'm currently running a Linksys WRT1200, actually happy with it, but decided to switch to a bigger device with 4 antennas and better wifi coverage. So the WRT3200ACM was my first choice, but now not sure after reading about all the wifi issues and also the missing WPA3 (which I didn't need yet).
There have been other threads about the WRT3200 being a good choice or not:

..I followed this one one month before and wanted to reply but then the thread was closed.

Alternatives so far are in that order of priority:
Netgear R7800
ZyXEL NBG6817
Linksys EA8500
NetGear R9000 (Nighthawk X10 AD7200)
About the R7800 there was said in the other thread, that the wired performance is questionable.
I need all the features:
Main Access Point for around 10 devices in the home, 2,4GHz and 5GHz, wired router for 1000base ethernet, VPN Gateway (lower bandwidth of about 100MBit for WAN) but not sure which type of VPN I'll run, maybe later running some network services like Webdav, NAS, ZNC...
The Netgear R7800 and the ZyXEL NBG6817 seem to be the best alternatives, if not choosing the WRT3200AM which is still not a bad decision in some cases. So if both the Netgear and the ZyXEL are based on the same QCA IPQ8065 design (SOC and QCA9984 wlan), what differences are there?
I definitely preferred the Linksys WRT???? series look and stackable casing over all the others, also being a strong casing for mobile use. But this only being a matter of taste, the functionality should be more important.

This one comes with an older/ slower SOC (ipq8064 vs ipq8065) compared to the r7800/ nbg6817, both CPU speeds and wireless chipset have been improved since. As another drawback the ea8500 is only using a single CPU port to the switch, while all others use a dedicated CPU port for WAN and LAN (so two). Unless you find it very cheap, I'd go with the more current options.
Not supported by OpenWrt - and not very likely to gain support in the future (exotic SOC, with very little mainline support).

I accidentally got the R8000 — and I'm very happy.
This and is it fully supprted?
Yes and yes.
But I read this on project page: Devices with Broadcom WiFi chipsets have **limited OpenWrt supportability** (due to limited FLOSS driver availability for Broadcom chips). Consider this when chosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See [Broadcom WiFi](https://openwrt.org/meta/infobox/broadcom_wifi) for details.

This is a General warning for devices with Broadcom.
2 x 5 GHz, 2.4 GHz, switch work fine.

The warning about Broadcom wireless chipsets is correct, but the r8000 is a special case - as it's one of the very few routers with brcmfmac (mainline) supported wireless.
So I'm understanding that the R8000 is a better option (meaning faster Wifi) than the previous R7800 although it has half the RAM?

Actually, the more I read, the less convinced I am for both. r7800 seems lacking as CPU and I understand that it handles maximum up to 700 Mb / s WAN <-> LAN. r8000 has a non-open chip. I am increasingly oriented towards a 64-bit AMD quad core. It won't perform very well, but it will be better than these supermarket routers.

I have not said that, also the r8000 is about 2 years older than the r7800, with half the RAM and only 21 Ghz instead of 21.7 GHz CPU performance.
I can not rate the wired routing performance of BCM4709, but at least the r7800's QCA9984 wireless is going to be better than BCM43602 in the r8000.
It’s not the CPU that’s bad. It’s actually very good. It’s the Ethernet.
