Redline rules in my book. I too can't justify using it over Mobil1 given my oil change intervals.
I use their MTL in my manual gearboxes and it makes them shift like a hot knife into butter. I would not use any other oil in a manual trans and I've tried many different brands.
I also use Redline oil in the rear diff., but have also used Mobil 1 as its much easier to obtain.
