Corsair Dark Core Pro (2020) vs Razer DeathAdder Essential Left-Handed Edition (2013)
Razer DeathAdder Essential Left-Handed Edition (2013)

The Corsair Dark Core Pro is a great Gaming Mouse for its $71 asking price.
The Razer DeathAdder Essential Left-Handed Edition (2013), however, is merely passable at its $249 price point. If you're considering buying a Gaming Mouse in the $140 range, you might want to check out some of its competitors.
Two highly trusted sources that perform well-thought-out in-depth testing consider the Corsair Dark Core Pro to be a great product - it earned the "Best for Cord-Cutting Serious Gamers" title from PCmag and "Best Qi wireless charging gaming mouse" from Tom's Guide in their respective Gaming Mouse roundups, which is a good indication of it being a notable product.
As for the Razer DeathAdder Essential Left-Handed Edition (2013) - CNET, a source that conducts reliable hands-on testing, has featured it in its Razer DeathAdder Left Hand Edition review roundup. However, it didn't make it to any of the top spots.
We couldn't find any sources that tested both of these Gaming Mice, so we only analyzed how they performed in reviews from different sites.
We first examined which sources rated each of these best and found that the Corsair Dark Core Pro got its highest, 9, rating from Tom's Guide, while the Razer DeathAdder Essential Left-Handed Edition (2013) earned its best, 7.5, score from CNET.
Lastly, we averaged out all of their review ratings and observed that the Corsair Dark Core Pro, with its 8.4 average, performed considerably better than most Gaming Mice - the mean score for the product category being 7.5 out of 10 - while the Razer DeathAdder Essential Left-Handed Edition (2013) managed an average of 7.5.
There's one caveat here - it might not be entirely justifiable to do a direct Corsair Dark Core Pro vs. Razer DeathAdder Essential Left-Handed Edition (2013) review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
