Silverstone are first party suppliers of PSU's, I'd rather have a good warranty and excellent product, instead of an excellent warranty and acceptable product.

The Silverstone is a better product, I personally value that the most. It being cheaper is just a nice to have.
Silverstone is mid level PSU brand with very few high end models.
Even flagship Strider Titanium is basically designed just to check that efficiency box for advertising and is otherwise standard.
And you can't directly compare scoring of different sites.
Tomshardware has way more detailed and stricter testing.
While that eTeknix review is toward "sloppy" to put it nicely:
Remembering to make big number of Chemicon primary capacitor.
But only checking that secondary caps are unknown without bothering to tell what they are.
That makes me suspicious they're real cheapos and he didn't want to say anything bad!
I mean if you go through the trouble of tearing PSU open to that level, why else not tell reader what those secondary capacitors are?
(and 3.3V regulation is very far from excellent)
And I would rather have that cheaper cap in primary and expensive ones in secondary:
If PSU's primary dies (any problem there tends to cause fast self destruct because of high voltage) secondary loses power and simply shuts down.
But if secondary goes bad because of capacitors, there's risk of damage to components, or at the least increased wear from excessive ripple.
Whose filtering relies on secondary capacitors staying in good shape.
And that's about the most demanding and stressfull job for electrolytic capacitor needing high quality capacitor to last.
