I’m not saying the NBN isn’t a trash fire of an infrastructure project (it is), or that our 4G is bad (it isn’t), but at least for me I get rock solid 100/40 on HFC, which is for sure better than my NBN service in inner-North Melbourne
40 odd km from me there are estates wired up with NBN's original FTTP. Yet in my location, all that's available is the hopeless Sky Muster satellite service, which tends to go offline for days at a time, and has trouble with weird contingencies like rain. It was originally slated as a last-ditch option for people in truly remote areas, but the hapless NBN Co has gradually extended its use to anywhere they can't be arsed to serve properly.
[Edit: as a side note, my location shows the corporate fakery behind the 'mixed tech' model. Using a cheap 4g modem from ebay, and without even so much as a fixed antenna, I can get 60Mbps down with 4g. Yet NBNCo doesn't make the fixed wireless option available here, instead foisting on us the 'outback solution' of satellite with its 600ms ping times, pitiful data caps & unreliability]
Each technology has their own hardware faults though, and I've witnessed both. But as a user of the service, I'm actually surprised how decent HFC has been working.
My parents of FTTN get about 50/20,which is what I expect a lot of users on these lines would only be able to access. But the sheer cost of using a NBN over 4G makes it a lot easier to sell, data sims are not cheap
I no longer have a FTTC connection to test, but I don't think it's 3ms low.
Using AussieBB. It's around 20ms from Sydney to Melbourne on our routes
