Then there's Plusnet (Openreach) at £30.99 for 900/110. Personally I wouldn't want to pay more to Zen for effectively the same product. I absolutely wouldn't touch Vodafone with a bargepole! Plusnet support is excellent and you always get to speak to someone who knows what they're doing should you need support. They're also more than happy for you to use your own equipment and will actively support you should you wish to go that route. Over the past few years I have been with both Plusnet and EE and when switching either way there has been no difference whatsoever - apart from the cost and the 'extras' EE has, like TV.
Do you run any servers or anything on your network that would benefit from a 110Mbps upload? I have a NAS and run lots of docker services like Nextcloud and when outside my network connecting to my NAS I have never found 110Mbps to be in any way restrictive. Access to my OnlyOffice server is faster than accessing Office 365 (or whatever they call it now), or Google Docs. Think what you might need to do with that symmetrical connection should you have it. Clearly 900Mbps upload is better than 110Mbps, but for most it's just a number and would have no impact on what they do. Ping and jitter are way more important - and on my Plusnet FTTP broadband I'm currently seeing a ping of 5ms with both download and upload, and 0ms jitter.
