I recommend trying a Topre switch keyboard because they're very high quality and quieter than most, if not all, of the Cherry-type mechanical switch keyboards. In my opinion, Topre switches have the best feel for typing.

The downside of wanting a Topre switch keyboard is that your options are very limited. Topre makes a line of keyboards under the brand Realforce. They also license or sell the technology to PFU for the Happy Hacking Keyboard Pro 2 and to Leopold for the FC660C. They formerly licensed the tech to CoolerMaster for the Novatouch TKL keyboard. There may be more options now, but I haven't checked recently.

I use a Topre Realforce 87U keyboard and a CoolerMaster Novatouch TKL. They're the two best keyboards I've ever owned.
