We've tested more than 20 Logitech keyboards. Logitech keyboards are available for a wide variety of uses. They make keyboards with rubber dome and scissor switches designed for office and mobile use and also have mechanical keyboards geared towards gaming. The type of Logitech keyboard you need all depends on what you're going to use it for.
Logitech is known for its office keyboards, and the best Logitech wireless keyboard we've tested for this use is the Logitech MX Keys. It's a well-rounded model that provides very good performance for the office. It doesn't have as good ergonomics as the Logitech ERGO K860 Wireless Split Keyboard, but we recommend it because the K860 has a split design that not everyone may be used to; however, you should get what you feel comfortable with. This keyboard is well-built with a solid metal frame, and it even has white backlighting so you can see the keys easier in the dark.
It only connects to devices wirelessly, either through Bluetooth or the USB receiver, and latency is a bit high for gaming with those connections, but it's fine for typing, and you shouldn't notice any delay. It has multi-device pairing with up to three devices at once, and switching between them is easy. Typing feels great, and the keys are indented to help reduce typos. It's compatible with the Logitech Options software, which allows you to reprogram some function keys to a preset list of commands. Overall, it's the best Logitech keyboard that we've tested for the office.
The best Logitech gaming keyboard we've tested is the Logitech G915 LIGHTSPEED. This low-profile, mechanical keyboard is an incredible choice for gaming, thanks to its outstandingly low latency. The proprietary GL Tactile switches we tested have a very short pre-travel distance, so they should feel very responsive. Also, it's available with GL Clicky or Linear switches, so you can get the feel you prefer. You can customize the RGB backlighting on a per-key basis through the Logitech G HUB software. Since it's wireless, you can pair it with two devices and easily switch between them with the press of a button. If you don't need wireless connectivity, the Logitech G815 LIGHTSYNC RGB performs almost identically, but it's a wired model.
Due to its thin design, the metal frame flexes, and our unit came with a slight upward bend. The keycaps are ABS plastic, which easily picks up oil and may develop shine over time. Also, you can set macros only to the dedicated macro keys on the left side of the board, but you can't reprogram any other key. However, you can have up to three profiles saved to the board, so you can switch between them to give you more customization layers. All in all, this is an incredible gaming option.
The Logitech K380 is the best Logitech keyboard for mobile devices that we've tested. It's a simple keyboard that's smaller than the Logitech K780, but that means it's easier to carry around as you can easily place it in your bag. Build quality is decent, and even though the frame flexes a bit, it still feels solid overall. It comes with a few extra features like media hotkeys so you can play your favorite music easily, and you can reprogram a few function keys to a preset list of commands using the Logitech Options software.
Unfortunately, it doesn't have a proprietary receiver and can only connect over Bluetooth. This is good if you need to connect to your phone or tablet on the go but may pose a problem if your desktop computer doesn't have Bluetooth support. It doesn't have backlighting like the Logitech MX Keys, so the keys may be hard to see if you're in a dark environment. Typing quality is good as the scissor switches have a low pre-travel distance and offer nice tactile feedback, but they may feel heavy to press at times. The keys are well-spaced out and are slightly indented, so you know you hit the center of the key. All in all, it's the best Logitech keyboard for mobile devices.
Logitech has a wider range of options than Corsair, including office keyboards, as Corsair mainly focuses on gaming keyboards. Mechanical Logitech keyboards use proprietary switches, while Corsair uses Cherry MX switches. Overall, Corsair makes better-built keyboards, and their gaming options tend to have more customization options like setting macros to any key.
On the whole, Logitech and Razer are very different in terms of what types of keyboards they make. Logitech has a wide range of keyboards, from gaming keyboards to mobile models. Razer has a small lineup and focuses on gaming keyboards, but they've started to produce mechanical keyboards aimed at office use, and they're available in different switches. While Razer's Synapse 3 doesn't work on macOS, it offers more customization options than Logitech, like allowing you to set macros to any key.
Overall, Logitech makes good keyboards for any use. Their office keyboards are available in ergonomic designs or are portable enough for mobile use on the go. In terms of gaming, Logitech makes mechanical keyboards that almost any gamer should be comfortable with, but they aren't as customizable as the competition. Although it may be overwhelming to look at the list of Logitech keyboards and try to find the one that suits you, they'll likely have the right keyboard for your needs.
