I have a Ducky One Mini, so a 60%.
Likes: Better build quality than most plastic-case boards. Genuine Cherry switches, while not quite the selling point they used to be, are better than commodity clones. Convenient DIP switches for a few common settings. Everything just generally feels decent and solid.
Dislikes: Not hot-swap, though I think the One 3 might be?. Kinda pricy at MSRP, but if selection is limited then it is what it is. I do thoroughly dislike that for my board the complicated and obtuse on-board remapping/macro functionality is the only way to do it. If either of the ones you're looking at supports on-PC software, even Windows, do it. This may be less of an issue if this will be your primary board and you won't have to change things up often.
Along with Filco, they sort of are what they are: high quality but non-hobbyist Taiwan-designed boards with design philosophies that are just now creeping out of the 2010s. That's not strictly meant to be a criticism. I often use boards that are literally from early 90s, but it does sort of describe a certain set of expectations about materials, performance, programmability, etc.
