Im also using g203 lightsync,great mouse,been using it for almost 2 years!i agree its all preference, im using g203 lightsync because it was on a black friday deal, before was using g203 prodigy but after years of use mouse buttons would unclick and reclick when held in. probably put thousands of hours of clicks into em though so its to be expected. some people like razer mice. not really any end all mice, different ones come with different software to adjust dpi/polling rates and customizable inputs etc
