Logitech G502 Proteus Spectrum (2016) vs Logitech G903 LightSpeed Wireless Mouse (2017)

Analysis:

Two highly trusted sources that perform well-thought-out in-depth testing consider the Logitech G502 Proteus Spectrum (2016) to be a great product - it earned the "Ranked 1 out of 7" title from Laptop Mag and "Ranked 1 out of 6" from Tom's Guide in their respective Gaming Mouse roundups, which is a good indication of it being a notable product.

Taking a look at the Logitech G903 LightSpeed Wireless Mouse (2017), we found it was well-received by reviewers from a couple of reliable sources that conduct their own hands-on testing, including PC Gamer, PCGamesN, Windows Central, and Android Authority. It performed great in their Gaming Mouse roundups - it managed to earn the "The best wireless mouse for Apex Legends" title from PC Gamer, "best left-handed gaming mouse" from PCGamesN, and "Best wireless" from Windows Central, which is a notable accomplishment.

We examined all of the review data that we could find and first took a look at sources that reviewed both of them, like PCmag, and found that they haven't shown a preference for either product.

Then we checked which sources liked these two Gaming Mice best and found that the Logitech G502 Proteus Spectrum (2016) got its highest, 8, review score from reviewers at PCmag, whereas the Logitech G903 LightSpeed Wireless Mouse (2017) earned its best score of 9.3 from GBAtemp.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Gaming Mice on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Gaming Mice being 7.5 out of 10, whereas the Logitech G502 Proteus Spectrum (2016) and Logitech G903 LightSpeed Wireless Mouse (2017) managed averages of 8.0 and 8.9 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Logitech G502 Proteus Spectrum (2016) vs. Logitech G903 LightSpeed Wireless Mouse (2017) comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
