Corsair K55 (2016) vs Cooler Master SK621

Analysis:

The Corsair K55 (2016) is a great Gaming Keyboard for its $49 asking price.

The Cooler Master SK621, however, while a reasonable product for $239, doesn't stack up against its competitors quite as well. If you're considering Gaming Keyboards in the $210 range, you might want to check out some better options.

The Corsair K55 (2016) was loved by reviewers at TechGearLab, a highly trusted source that performs reliable in-depth testing. It did great in its "Best Gaming Keyboard" roundup where it was named its "A Budget Full-Size Keyboard", which, in itself, makes it a product worth considering.

Returning to the Cooler Master SK621, Tom's Hardware, a source that's known for its high-quality in-depth testing, has great things to say about it. In fact, it was named its "Best Travel / 60% Keyboard" in its "Best Wireless Keyboards for 2021" roundup, which is quite a feat.

We couldn't find any sources that tested both of these Gaming Keyboards, 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 K55 (2016) got its highest, 9.4, rating from Gadget Review, while the Cooler Master SK621 earned its best, 8, score from kitguru.net.

Lastly, we averaged out all of their review ratings and observed that the Corsair K55 (2016), with its 8.8 average, performed considerably better than most Gaming Keyboards - the mean score for the product category being 7.3 out of 10 - while the Cooler Master SK621 managed an average of 7.3.

There's one caveat here - it might not be entirely justifiable to do a direct Corsair K55 (2016) vs. Cooler Master SK621 review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
