I "benchmarked" the network across a few big VPS providers, they all seem to do 400Mpbs+ within the continent and 100-200Mpbs when you go across the ocean (iperf3, I assume you also meant heavy sustained traffic). It also aligns with what the creator of PHP found out: https://toys.lerdorf.com/low-cost-vps-testing. Did you find a provider where the network would allow you to go 300Mbps+ across the ocean on a cheap VPS?
Re: CPU, if you were comparing them with the VMs from "the big 3", you should look under the "Dedicated vCPU" tab: https://www.hetzner.com/de/cloud
My 7 Euro hetzner cloud instance in Falkenstein easily does about 5Gbit (inter-europe).
From my experience, at Hetzner you are very rarely limited by their network. Usually only by poor peering from transits. Peerings with all the big names are great tho, so no reason to complain for me.
And from what I know from someone near Hetzner, they don't cheap out on peering at all.
Yeah, heavy sustained, and DO came up on top (even your link says so). Admittedly, I haven't tested across the pond. I've tested dcpu ones only AND only for my load (node.js with a worker). That's why "benchmarked" is in quotes. :)

I can easily imagine cost savings on Hetzner could benefit certain loads, of course. It's always "depends".
I don't see Hetzner dedicated vCPU's on there? I did mention "dcpu" ones. But thank you for your benchmark, it's very useful for shared-cpu comparison.
How did I come to it? Measuring performance of my node.js service I need to run on it, iperf, speedtest.
