From what I've been reading sky fibre is the best. Virgin apparently has latency issues and poor upload speeds, and they also have a problem with traffic at peak times which caps whatever internet package you have anyway.
It's their superhubs, they have a latency like the superhub 3 I use. My gaming is fine with little delay but the more matches I play the worse the latency gets (as worse as seconds behind other players) which is unbearable. My guess is the superhubs are the issue, they're not stable enough, but hopefully they fix it but then again I've had this issue for 2 years
I've run a number of diagnostic checks on both your Hub and local network segment and both report back in good health, with pretty much zero peak time contention on both up and downstream channels, so the slow speeds and high latency is a bit of a mystery.
It would be helpful if you could drop the Hub into modem mode and try a direct connection to your device/console bypassing your router and let us know how the speeds/latency are looking.
hmm yes the moderator dismissing the Hub 3's faults is the usual ploy, however even so with the latency being consistently above 100ms would indicate another problem, might be worth posting your upstream/downstream stats and the network log.
