Don't look at the Type-S as a better HHKB, or an upgraded Pro 2. It's simply not. It's just a different experience.
I spent weeks looking at the keyboard before finally ordering one to go alongside my Pro 2. I sat down and typed on it and was pretty underwhelmed, as I was kind of expecting more. The first time you type on a HHKB, it's a really unique and awesome Topre experience, but the Type S isn't that way. Don't get me wrong, it's still a great keyboard. It's just a different sound and feeling, not necessarily better or worse.
Lubed, the Type-S is pretty quiet. I used mine at work for a long time before getting a secondhand 55g 87U Hipro. I've always been partial to the sound and feeling of silenced Topre switches, so I will most likely put some Hypersphere rings on my current board.
