When you mean good, do you mean life expectancy and running time MeepsterNotchy.
If so first of all they won`t be cheap compared to other branded capacitors.
Plus they will have a higher tempreture rating in tolerance.
And better ERS rating.
The only way to tell is by pulling up the specification sheet of the component for it`s electrical quality.
As a rule of thumb a capacitor with a higher heat tolerance
will last far longer in working life hours.
