I use to always use shell V power in one Honda, and tried E10, lead to check engine light for cat. It was supposed to be ok as per honda uk website but - Being compatible and being safe / best are not same
I had done mpg calculations in past on v-power and normal fuel and it was different, engine exhaust smelled worse with E10 and slight shake in engine in one Volvo disappeared with with use of V-power
Using shell v-power once couple of months might help with the detergents etc clean up the engine/system? If not driving 5 figure miles, the difference of cost might be not worth it. I say E5 might be better option - I would be happy to play safe.
