Openreach will offer symmetric packages this April 2025 but of-course none of us know yet, which ISPs will be offering those services. I'm aware it is going to be extremely expensive at £122 a month!
But I expect that in future prices will go down naturally. The strongest point of Openreach is that they offer their packages to 650 different ISPs. You have a much larger scale of options to choose from with more router choice.
Of-course my original post was speaking from my perspective having Community Fibre already that does have symmetrical speeds. The problem is that they no longer offer to have CGNAT removed for their 500Mbps/1Gbps packages. You now need to opt for their 3Gbps. This is especially a problem when you require port forwarding particularly for old style games that use Games for Windows Live or other games like S.T.A.L.K.E.R. Clear Sky where you cannot host your own Multiplayer servers or join servers.
From my point of view of-course symmetrical speeds is less relevant. I'd still in some respects prefer to have Openreach as a second network provider compared to Virgin Media. Because like you say they don't have IPv6 while it may be no big deal at least I would have more choice on Openreach like with BT presently do. The danger of price hiking is always there. VM will drastically hike up their prices unlike other Altnets. If you only have VM available and it is the only anchor ISP on the nexfibre network they will take advantage and can price hike.
There are reports even on these forums that people who have another Altnet available, use this as a tactic to haggle with Virgin Media to get their prices down! If you have multiple choices or ISPs then VM and others cannot monopolise you!
There's also no ONT, you are stuck with their router, which if you want to use your own you have to put it in modem mode since most routers don't have a Fibre SFP+ port. You need a special router that has SFP+ port to directly plug the Virgin Media Fibre cable into it.
You could buy a media converter. I did that recently in my home because I decided to run a fibre cable from my switch downstairs to the bedroom upstairs. I'll add an SFP card to my desktop eventually but the media converter does the job for now.
Ok, that's great to know! But I just had a look at those media converters and the majority of them are only 1Gbps support. What happens if you chose a 2Gbps package on VM? Then that Media Converter will not support those speeds and you will be capped at 1Gbps.
I cannot find a media converter that supports higher than 1000Mbps. I have found this
https://www.startech.com/en-gb/networking-io/et91000sc2 while it claims to support Maximum Data Transfer Rate 2000 Mbps (full duplex mode) the title and the name still shows as 1000 Mbps and it costs £197.99 GBP incl. VAT!
I could buy a new router like the rt-ax89x that seems like a more rational choice

That has the 10G SFP+ port included. But that still means I have to shell out for a new router should the Virgin Media hub be causing problems. Maybe, just maybe like others have mentioned on these forums if in future other ISPs join the nexfibre network they might offer to either install an ONT or they will manufacture a special router similarly like the Hub 5x that will have an SFP+ port included.
