Choose the AL21 if its aluminum case, sound-dampening foams, and vendor-described remapping and macro functions suit your desk or creative workflow. Choose the YZ19 if low weight, a tactile switch option, or XDA-profile keycaps matter more. Both share tri-mode connectivity, a knob, and hot-swappable switches, so those features do not distinguish the two.

What will you mostly use it for?
The AL21 has the stronger case for office work, programming, and creative workflows, based on its aluminum construction, sound foams, and vendor-described remapping and macro functions. The YZ19 is the travel-oriented pick because it weighs substantially less. Gaming and modding are closer calls: both offer N-Key Rollover and hot-swappable switches, with different switch choices and customization details. Both models have south-facing LEDs, so buyers considering shine-through legends or certain sculpted keycaps should check fit and lighting expectations.
It's a tie
- Both list N-Key Rollover and 2.4 GHz, Bluetooth, and wired connectivity.
- The AL21 uses linear switches, while the YZ19 offers linear or tactile switch choices.
