Gutted !!!!!!! My local Shell (and the only one anywhere near by) has changed to a BP overnight

So when my GTI arrives, I have the choice of BP Ultimate or Tesco Momentum 99. I believe Tesco is better as it's 99 RON vs BP'S 97 RON, although I f**king hate Tesco !! I don't think it's Tesco's fuel I believe they buy it from someone else, so I guess that makes it ok. Interested to know what people would use if they had the choice of BP Ultimate or Tesco 99 ?
The car is going to be mapped.
Why oh why has Shell changed to BP .. gutted! :embarassed:
Cheers,
Scott
