The HHKB variants can be nice keyboards, but they're definitely not for everyone. I have a Leopold FC660C that has the same silenced Topre switches as some of the HHKB variants and they're really nice, but the boards that come with them quite expensive for what they provide. The HHKB layout can also be a bit annoying to get used to too, which is why I use the FC660C, since it has arrow keys.<p>In practice I find modern custom keyboards to have higher upside than Topre keyboards, since you can build one with your preferred layout and switches. If you get a QMK enabled board you can also fully customize the functionality of the keyboard, which I find immensely useful. Unless you specifically want a 60% keyboard with light tactile switches I wouldn't recommend an HHKB, but if that's what you want it's hard to do better.
