It's great to see a company take a nearly perfect product and iron out its last remaining kinks. The Logitech G500s was a top-notch all-purpose gaming mouse, but its successor, the Logitech G502 Proteus Core, surpasses it in every way.

While the Razer Mamba ( at Amazon) is more expensive, its adjustable click feedback and superior lighting keep it as our Editors' Choice.

The only discernable difference is that the Spectrum nixes the Core's teal highlights in favor o...
