UC from LHR to LAX

I need to book flights for May next year and can't decide whether to go for VS UC or DL BE.
Do either of the VS flights have the new UCS? If not, is the entertainment system the old style with the battered-up TVs? Have the old UCS been refreshed any time recently? I flew the old UCS to JFK and it was looking very tired and it annoyed me having no power outlets/USB ports and such an old entertainment system. Conversely, DL BE was fantastic on my transcon LAX to JFK flight earlier this year, so I will choose it for this trip unless there's a better reason to stick with VS. I assume I'll still get Clubhouse access? And Revivals access on arrival back into LHR?
Thanks for any advice!
