If you look through the UOA's, you'll find that they're both fine oils.
At my local auto parts store, however, the Castrol is 38% more expensive than the Havoline. There's no way that it's a 38% better oil.
If you can find it on sale for less than the Havoline, then go for it. Otherwise, I'd source some more Havoline, or maybe Chevron Supreme, which is practically the same stuff.
