If you liked the Frog TKL, I’d look at kits with a solid aluminum case, good mounting options, and a well-tuned PCB rather than just chasing the newest release. The Cycle8 and Neo80 are worth checking out, depending on your budget and whether you prefer a softer typing feel or a firmer, more substantial build.
If you want something more premium, the Cycle8 is another one I’d shortlist, though I’d check current stock and pricing before deciding.
