PFU Happy Hacking Professional 3 Hybrid vs Cooler Master SK621

Analysis:

The PFU Happy Hacking Professional 3 Hybrid is a great Mechanical Keyboard for its $367 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 Mechanical Keyboards in the $210 range, you might want to check out some better options.

The PFU Happy Hacking Professional 3 Hybrid was loved by reviewers at PCmag, a highly trusted source that performs reliable in-depth testing. It did great in its "The Best Mechanical Keyboards for 2021" roundup where it was named its "Best for Minimalists, Programmers, Fans of Topre Key Switches", 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 Mechanical 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 PFU Happy Hacking Professional 3 Hybrid got its highest, 8, rating from PCmag, 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 PFU Happy Hacking Professional 3 Hybrid, with its 8.0 average, performed considerably better than most Mechanical Keyboards - the mean score for the product category being 7.4 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 PFU Happy Hacking Professional 3 Hybrid 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.
