I don’t think “anything close” is even vaguely true. I have openreach FTTP at 900mbps down, and the bandwidth is the same or better than I ever got with virgin gigabit. I’m also about to switch to another FTTP provider who provides 900mbps down 900mbps up for £25 a month. Plus with both of those I can pay a little extra to have a monthly rolling contract.
Additionally my average latency dropped by more than half when ditching Virgin. I was genuinely shocked at how much better it was.
