I haven't used Topre switches, but I've had a Das Keyboard Quiet with Cherry MX Silent Red switches for over 10 years now. And I second everything you say about them. I also don't mind the linear feel, since I do a fair bit of gaming with it in addition to work. And even in the middle of some fierce button mashing, the noise is enough to confirm to me that I'm hitting the key, but not enough to distract from what's going on.
