Shell is good but personally a rip off at RM1.57/L!! Best to just use a high octane fuel of 97RON. The best value is Esso/Mobil.
Note however that a number of ECU tuners have said they can tune out more power with Shell V-Power without knock compared to others??...
Also note that many FDs blow not because of fuel choice but because of insufficient A/F ratios due to big exhaust / intake / DP and Stock ECU. That is heaps of air but not matched with extra fuel. Not to mention that the stock ECU is mapped to only 0.9bar. Best to get an A/F meter & fuel pressure meter to ensure you are not running lean or that your fuel pump is not struggling at those high revs that we all love!
