kendall gt-1 0w20 and Castrol 0w20

[disneyfire]

Both kendall GT-1 and Castrol 0w20 synthetic, is a couple of oils i can't find much info on..Not gold bottle castrol but the black one.
Are these "either or" oils or does one have a "better" additive pack?

The Kendall I've used for a couple years. Great quality oil and the liquid titanium additive is a nice alternative to zinc. I stoped using it and after 20,000 miles the titanium still shows up in my uoa
