RBK763 and RBK763S - differences?

Question

I've been looking at picking up a set second hand, however some people are selling a set of RBK763 but some are RBK763S, whereas for a new set on Amazon for example it's only listing the RBK763S. I'm trying to work out exactly what's different. As far as I can tell from the datasheets, the only documented difference is that the RBK763S includes a year's sub to Armor (RBK763 having a 30 day trial), and that the RBK763 nodes have 6 antennae to the RBK763S's 4.

They otherwise look to run the same firmware, and have the same user guide.

Also I saw in a review of the RBK763S (https://mightygadget.co.uk/netgear-orbi-760-tri-band-wifi-6-mesh-system-review/) that it will run the backhaul wireless channel using a 160MHz channel width but I've no idea where that info comes from as I can't see that in the Netgear docs for either system, any idea if that is correct? And if it applies to both the RBK763S and RBK763, if so?

And is there anything else beyond the above that's different between the two? I'm trying to see if one is "better" than the other, basically. Although either is undoubtedly going to be ahead of the RBR20 and a couple of RBS20's that I've been using happily for several years.

There are no HW differences between the S and non S version.&nbsp;
&nbsp;
If the conditions are good and optimal, then the system could run the BH at 160Mhz, however if building materials and distances are a factory, then BH maybe more at 80Mhz. All depends.&nbsp;
&nbsp;
The 760 series is based of the 350 series hardware. FW was just released by NG. No idea if there will be continued FW builds. You might consider a 750 series or maybe a 850 series. More mature and stable systems.&nbsp;

Thanks. So the number of antennae listed differently on each datasheet is incorrect, then? I have also been considering the 850, but the cost difference is pretty high - although I'm not entirely sure I need two satellites anyway really, which would help reduce cost (in either case)!

Is there not much different in the way of performance between the 760 and 750 series, either? I was just assuming newer=better, ultimately my need is to have solid use of a 500Mbps fibre connection that will be installed next week, in a combination of multiple devices using it at once (some directly using the internet, some using a connected Synology NAS), and with decent range (from house over to garage, for one satellite). This is with all with wireless backhaul. The old RBK23 I'm using isn't bad, but it's definitely going be right up at its limit.

What's the size of the home in Sq feet?&nbsp;

The&nbsp;house isn't huge, ground and 1st floor, about 700sqft each floor. Add about the same 700sqft for back garden/garage (garage is 1st floor height) and say 500sqft front garden. I've actually just drawn it up (attached), it's more or less to (some sort of) scale, shows the setup as it is at the moment.&nbsp;&nbsp;Currently the RBR20 sits near the fibre access point. One RBS20 is upstairs, the other is in the living room. I actually switched off the satellite in the living room a few days ago as a test, as it's got direct line of sight from the router and has been working fine without (low bandwidth requirements, 100Mbps at most - it's there because I needed something wired into it once). The upstairs satellite just about reaches the garage, but it's at its limit. The whole system works well in general, but given our internet connection is about to get about 7x faster I want to be able to not have any sort of bottleneck on the network side.&nbsp;So I'm looking for a bit more coverage, and a more consistent ability to be able to make use of a full 500Mbps connection from multiple locations, while other throughput is ongoing elsewhere on the network (eg NAS serving things up at the same time). And fully wireless. Seemed like either a couple of 850's or three 760's would be more than capable of what I want (and, secondhand, at not too dissimilar a price, and in the range I'm willing to spend), but happy to hear suggestions.&nbsp;

An RBR and just 1 RBS should be enough then. Two, would recommend running the power at 50% or maybe 25%.&nbsp;
