Which is preferred?

[gastorgrab]

If someone needed a cap, 1000uF, 6.3v x 8mm and had the choice between a lower quality cap with the correct specs, and a higher quality part with slightly wrong specs (1000uF, 10v x 8mm), which would be preferred?

The one with the lowest resistance?

Shure, the one with sufficiently low ESR and from the most reputable vendor.
Even some higher ESR would be tolerable, instead of using the crap brand.

Higher voltage is always not a concern, as long as physical diemsions do fit (and you not overdo it e.g. a 200v cap has very likely a higher ESR than e.g. a 50v ones).

So if you have the choice between super low ESR from crap brand and a not that low ESR cap like Pansoic FC or similar, i think is is oviousely, wich to use.

The important thing is, that the specs from the high quality brand is somhow guaranteed, those values from the crap caps are simply a number on paper witouth any meaning.
Just plain hot air, in wich those valuses will very likely disolve like the shugar in a hot coffee.
