Question Mobil 1 vs Amsoil

I realize Amsoil is sold thru MLM and they have a good story. I have used both Mobil 1 and Amsoil synthetic, with good results on both. I am looking at the longer drain interval quoted by Mobil 1 and Amsoil. My question is-- is one better than the other or are they about equal. And can they hold up to the 15,000 and 25,000 drain intervals they tout, I also realize that the filter will probably need to be changed at 10,000 mi. This is for my daily driver Toyota, P-car gets and oil change every 3K mi. or 6 months.
LubeMaster, any comments or educated opinions.
