Sky Mobile - any good?

[Zetec-S]

Currently have home phone, broadband and tv with Sky, been with them for years and no complaints with the service. I logged into my account earlier and it suggested I could get an iPhone 7 with 1GB/calls/texts for £25 a month, no upfront payment (24 month contract).

If I check my upgrade options with Vodafone the best they can offer is £36 a month (+£69 up front) for a similar deal, so I'm thinking of leaving and going over to Sky.

Pros for moving to Sky:
- Cheaper
- Network coverage suggests I'll get good reception at home/work/friends/family

Cons against moving:
- I know I get good (4G) reception with Vodafone at home/work/friends/family
- Could be too "tied in" to Sky so harder to threaten to leave and get a discount for the TV/BB package?
- No idea what the service is like for Sky mobile (vs 15 years with Vodafone with no issues)

Anyone with Sky mobile, and how do they find it?

Thanks for that, didn't realise it was O2. Think the Mrs is with them so should be good
