Vodafone Gigafast - which package? Any mobile tie-ins?

[Quartz]

Vodafone have made the fibre-optic cable outside my door live. I'm getting too many pauses on BT Infinity. So, should I go for 500 Mbps or 900 Mbps?

And are there any tie-in packages worth considering? My mobile is currently with EE on a SIM-only contract.

Yes, I'd prefer Zen over Vodafone. They're not offering fibre right now here. If memoiry serves, Vodafone will have exclusive rights for a year or two.
