According to this report there is an difference in gas.

Yes. The above specifications are intended to ensure minimal quality
standards are maintained, however as well as the fuel hydrocarbons, the
manufacturers add their own special ingredients to provide additional
benefits. A quality gasoline additive package would include:-
* octane-enhancing additives ( improve octane ratings )
* anti-oxidants ( inhibit gum formation, improve stability )
* metal deactivators ( inhibit gum formation, improve stability )
* deposit modifiers ( reduce deposits, spark-plug fouling and
preignition )
* surfactants ( prevent icing, improve vaporisation, inhibit deposits,
reduce NOx emissions )
* freezing point depressants ( prevent icing )
* corrosion inhibitors ( prevent gasoline corroding storage tanks )
* dyes ( product colour for safety or regulatory purposes ).

but the question is which Brands are better

Audi recommends Shell V Power. It was in an article of quattro quarterly that Audi and Shell work together on R & D
I have used Shell exclusively since I purchased my A5 and have been happy with it. FWIW when I had my last car (Infiniti FX45) I noticed that with Mobile I got about 1.5-2 MPG less and with BP I got about 1 MPG less than when I used Shell. For the last two years of ownership of that car I used Shell exclusively also.
