In all cases the difference in speed between same ring and different ring was less than 10% but also in all cases maximum throughput was a fraction of the advertised speed.
The Homeplug advertising, e.g. 200 or 600 Mbps, is what they call PHY and is similar to WiFi G saying 54Mbps for example. You can't get 200/600 or 54 out of any of these. In fact WiFi G topped out speeds of 22 Mbps on a real TCP/IP connection. You can't compare any of these technologies with the throughputs of Ethernet.
Don't expect a Homeplug AV200 to allow your VM 200 Mbps broadband to work in another room at 200 Mbps. You would need to buy the 600, or better the 1200 models - and have good clean electrical wiring.
NOTE: The USA home mains wiring is VERY different to the UK. They don't use "rings" as we have, so instructions on where to plug HomePlug units from the US are likely to be poor advice for UK homes.
For some real world testing (with graphs) have a look at Small Net Builder, for example:

and Solwise have some sensible recommendations:
