Logitech G502 Lightspeed vs. G903 Lightspeed: Which mouse is better?

Overall, the Logitech G502 Lightspeed is the better mouse in terms of design quality and maximum performance, but the Logitech G903 Lightspeed is by no means a slouch, and you can get your hands on it for a considerably lower price. It's also the better choice if you're left-handed.

G502 Lightspeed vs. G903 Lightspeed: Quality or price?

In terms of physical design quality, both the Logitech G502 Lightspeed and the G903 Lightspeed are top-notch. Both mice are built to last with sturdy frames and materials, and both come with 11 buttons that you can customize as in-game macros.

It's worth highlighting that the Logitech G903 Lightspeed was designed with an ambidextrous shape, which means that it works well for both right and left-handed users; the Logitech G502 Lightspeed is only meant for the right-handed.

One advantage that the G502 Lightspeed has, though, is that it has more possible weight combinations than the G903 Lightspeed thanks to its greater variety and number of removable weights. This is great if you like to fine-tune the weight of your mouse. Both mice are also compatible with Logitech's PowerPlay mat that will wirelessly charge them during play, effectively giving you infinite battery life.

When we take a look at performance, though, it becomes clear that the Logitech G502 Lightspeed is the clear winner in that department. Both mice have excellent optical sensors, but the Hero sensor that the G502 Lightspeed is fitted with is more accurate than the G903 Lightspeed's by a small, but noticeable margin. In addition to that, it also can achieve a sky-high DPI maximum of 16,000, which is 4,000 more than what the G903 Lightspeed is capable of.

The battery life performance is where the G502 Lightspeed really establishes its dominance, as it's capable of 60 full hours of usage time if you don't use the RGB light, which is nearly double the G903 Lightspeed's maximum battery life of 32 hours.

G502 Lightspeed vs. G903 Lightspeed: Which should you buy?

At the end of the day, I think that the Logitech G502 Lightspeed will be the better choice for most people looking for a high-end wireless gaming mouse. It's true that you have to pay more for it, but the increased optical sensor accuracy, higher DPI range, and more extensive weight-tuning options will very much come in handy if you're looking to take your gaming experience to the next level. The bigger battery life is great, too, as you won't need to worry about charging it very much.

However, it's important that I emphasize that the Logitech G903 Lightspeed is an option that you should absolutely consider. If you want something high-quality that costs a bit less and offers slightly lower, yet still similar performance — or if you're left-handed — the Logitech G903 Lightspeed is a fantastic alternative choice.
