Brother technically speaking you are right that Mobil 1 is top dog like Shell but the problem here is that in recent month Mobil 1 products are gone insanely high.
I bought the old stock in December 2013 for Rs. 3,550/- for Mobil 1 5W50 direct from factory (retail was 3,950/-).
Now the Mobil 1 I can find is available for Rs. 4,400 and my MAL connections are unable to provide me at discounted rates.
The LiquiMoly Synthoil is top grade LM oil and it competes with Mobil 1 Extended Performance which is not available in Asian regions.
So now I prefer LM over Mobil 1 due to Mobil 1 old formulation and price point only for my 9th Gen Civic.
For my 2010 Corolla and 2005 Prosmatec I use tried and trusted Mobil Super 2000 from 50L drum direct from factory.
