My subjective opinion, based on my experiences, is different than yours. I've not had wear issues with Mobil 1 15-50. Thousands of miles trouble free, most of it since 2005 with the "new" formulation of Mobil 1.
would be a boring world if we agreed on everything...

Experience counts but it all depends on your application road engine or road race engine, I think most of us realise that modern motor oils are lower on
Zinc, and
oil companies have listened to the performance car sector and the camshaft break in and wear problems and have designed oils to suit.
There seems to be a great emphasis on lighter weight oils rather than what the
oil package is, why would you use a modern catalytic compliant
oil, which is lower in
zinc when you can buy a number of oils recommended for flat tappet old style performance engines from oil companies.
Just for interest I read through the GM LS7 Crate engine start up instructions on the net, and they dont recommend
synthetic oils like Mobil 1 until you have done some break in work and after one preferrably two oil changes on mineral oil.
