Cherry MX Brown and Kailh Box Brown V2 are very similar, medium-weight, tactile switches. They have a fairly small but satisfying bump to overcome before actuation. The Cherry bump is in the middle of the keystroke, while the Box Brown switch bump comes earlier and feels a bit heavier. The Kail switches also have a box design, which means they're typically more stable and durable in the long run. However, there's also a bit of inconsistency in switch-to-switch performance as they're more mechanically complex.
Cherry MX Brown and Gateron G Brown Pro are switches with a small tactile bump to overcome during actuation. The Gateron switches feel a bit smoother out of the box as they're pre-lubed from the factory, while the Cherry switches aren't. Additionally, the Gateron switches have a clear upper housing for better RGB illumination.
Cherry MX Brown and Razer Orange Gen 3 are tactile switches with a small bump to overcome during actuation. While the Cherry switches are suitable for typing and gaming, the Razer switches are designed specifically for gaming. They're considerably smoother feeling from the factory with slightly better latency performance. They're also a bit more lightweight, and while they have the same amount of pre-travel distance, the tactile bump happens much sooner during the Razer's keypress.
Cherry MX Brown switches are tactile and have a small bump to overcome during actuation. On the other hand, the Razer Green Gen 3 switches are clicky switches. They're noticeably heavier-feeling and loud, making a signature click sound on the downstroke. Both switches offer the same level of latency performance.
Cherry MX Brown and Kailh Speed Copper switches have small tactile bumps to overcome during actuation. The MX Brown switches are designed for everyday typing and gaming. In contrast, the Kailh Speed Copper switches are designed specifically for gaming and have a much shorter pre-travel distance and significantly better latency performance.
Cherry MX Brown and Outeumu Brown are very similar switches with a small tactile bump to overcome before actuation. The Outemu switches are a bit smoother out of the box and have a clear top housing, allowing for better RGB illumination.
