I will say this. I USE to use Mobile 1 exclusively until about 7-8 years ago when I began using AMSOIL by recommendation from a friend that owns the local Carquest. I first used it in one of my Duramax pickups. I began doing oil analysis testing before I would extend my intervals. However, the first time I extended my intervals in my 03 Dmax, I was able to go over 18K miles on one change with the lab telling me to go another 7K miles and test again. I have also had customers who have seen over 35K miles on one oil change using analysis testing to determine their intervals.
Everyone has their favorite brands. All three options you asked about are good options. A good way to determine if one is better than the other is to take a good look at their manufacturer recommended service intervals. If they can warrant intervals up to 25K miles or one year, it is a good possibility that their oil is going to provide better overall protection, even when utilizing shorter service intervals.
The price is right as well. With current wholesale pricing, AMSOIL is not as expensive an option as it seems to be. Let me know if I can provide a shipped quote for you, that, along with more detailed information about their oil and filters can serve to help you to know everything you need to before making your choice.
