Define better.
They (Filco, Leopold, Ducky, &c) are all pretty similar visually, have thin ABS caps that get shiny, plate mounted switches, and even made by the same OEM. Some regard Filcos to have a higher build quality and warrant the pricier tag while others disagree; your subjective opinion may vary. See ripster's hypothesis of weight being proportional to perceived build quality.
Just spend however many quids as you're willing and able to afford. Getting the right switch is the bigger question, really.
