What will you mostly use it for?
The K2 HE is the more feature-oriented choice for gaming and programmable input, while its 75% layout also offers listed ANSI, ISO, and JIS variants. The J3 SE is a more straightforward fit for office work that benefits from a numpad, and it offers broader mechanical-switch replacement options. Travel is a trade-off: the K2 HE has a smaller layout, but the J3 SE has the lower listed weight. Both boards offer wireless and wired operation and QMK support.

“I love the keyboard! Everything was as expected but the keys are even smoother than I could have hoped for. I love the color, it matches exactly what was displayed on the website. Setup was very easy once I actually read the manual. I like that it gives you…”

“Lowering the actuation depth improved my reaction time in competitive games. Analog mode in racing titles feels surprisingly natural. The mouse glide is smooth.”
“I thought the macro didn't have infinite repetitions, but there are no helpful images anywhere on the internet. I still haven't found the answer.”
