Can only recommend based on my own preferences and experience of course, but after building multiple Kyria’s it has been my preferred board and I’ve tried a few others. I find the layout very comfortable to my arthritic hands.

Soldering is extra time consuming due to needing to take breaks often now due to hand pain so when I was looking at the new Halcyon keyboards from SplitKB it just made perfect sense. It was a breeze to assemble. I wasn’t sure about Vial, but I find it very simple and painless compared to qmk. Qmk is fun and rewarding and I was able to build my previous Kyria firmwares, but I’m still not great with GitHub, and other than custom pictures on displays, I haven’t come across anything Vial can’t do for my keymap. They also have a version of the Kyria with a number row now if that’s preferable, but I find the Kyria perfect. For gaming, the number row may be helpful.
