If you're playing games, the only keyboard you should choose is magnetic.
Eve Batt, a writer for Tom's Guide, which tests various new products and writes review articles, has posted about why he came to the conclusion that 'magnetic keyboards are the only choice for gaming' based on his experience reviewing many gaming keyboards.
Mechanical keyboards are dead — here's why you should only buy a magnetic keyboard for gaming | Tom's Guide

'There are countless great mechanical keyboards out there that are optimized for gaming and have excellent responsiveness and tactile feedback,' Bhatt begins the article, saying, 'However, in the past few years, the difference in quality between mechanical and magnetic keyboards has become more apparent, and many top professional gamers have switched to magnetic keyboards. I myself will probably only use magnetic keyboards from now on. In this article, I will explain why you, too, should switch to a magnetic keyboard.'
A magnetic keyboard is a keyboard that utilizes
the Hall effect,
which generates an electromotive force when a magnetic field is applied to an electric current. Magnets are embedded in the keytops, and a sensor on the base detects the movement of the magnet to recognize when a key is pressed.Since magnetic keys can read 'how much a key is pressed' with high accuracy, users can customize the criteria for 'how much the key is pressed at' according to their preferences. Mr. Batt sets it to 0.1 mm so that key input can be performed with just a 'slight touch,' but 0.4 mm is recommended in consideration of some errors.
Some products, such as Elecom's VK600A, can be set to 'turn on the moment you start pressing' or 'turn off the moment you start releasing,' allowing for quicker response to human input during games. This type of function is commonly called 'rapid trigger.'
Using Rapid Triggers means that there is almost no delay in key input, allowing you to perform your operations the instant you think they are in games that require quick reactions, such as FPS and MOBA games.
Since the keyboard can recognize the amount of pressure applied to the keys, it can also perform actions similar to those of an analog stick on a controller, such as 'pressing lightly to walk' and 'pressing deeply to run.' Many games do not support input based on the amount of pressure applied, but keyboard manufacturers have released settings tools that can be customized to 'press deeply to input the Shift key at the same time.'
'Magnetic keyboards are the only ones that allow for a variety of pressure-based customizations depending on the game,' said Bhatt. 'While it was a bit excessive for my gaming requirements, I'm happy to have this feature available for creative gamers.'
'I'm excited about the future of magnetic keyboards,' Batt concludes the article.
