What will you mostly use it for?
The main decision is whether you need a complete compact keyboard or an additional number pad. The Luma40 is the more direct fit for gaming, programming, and travel as a primary typing device, though its 40% layout is highly compact. Office use can go either way, depending on whether low-profile ortholinear keys or dedicated numeric entry matters more. The TH33 has the edge as a programmable companion for controls and macros.

“Wow, at first I thought it was gonna be useless because I don't use arrows nor numpad, that's why I use only 60% keyboard. When I recieved the TH33 I noticed that I can remap every single button. Now I use it as a budget stream deck, I put on matching keycaps…”
“It was what I wanted but the usability was not as good as I wanted. Software was very buggy and there are almost no alternative keycap options.”
