I agree with jpc above ^.
My favorite keyboard has become my RealForce 87U Silent. I also have an 87U 45g, but the 87U Silent is nicer. It feels luxurious and smooth, and of course quiet (but not entirely silent). Like jpc said, the Topre switches are most like MX Browns without the gritty feeling, although they are different as well since all of the tactile "bump" occurs at the top of the keystroke, instead of in the middle like the MX Brown. The regular Topre switches are nice, but the Silent version is just a bit nicer. However, the variable weighting may take some getting used to. Although once you get used to variable weighting, you will appreciate how great it is for typing (you will feel less fatigue in your hands and fingers). Now for gaming, I prefer my 87U 45g even-weighted switches, because the variable-weighting makes the WASD cluster feel a bit "off", since the "A" is only 30g. So if you are a big gamer, get a 45g board. Do not get a 55g, as 55g is too stiff for either typing or gaming, IMO. I just wish RealForce manufactured a keyboard populated entirely with the Topre 45g Silent switches, because that would be the best gamer board of all time. It would be smooth and silky, and nearly silent. And I would not have to switch back and forth from my 87U Silent for typing, and my 87U 45g for gaming. (Note: I have, or have had, keyboards with Topre Variable, Silent, 45g and 55g switches, as well as MX Blue, Brown, Black, Clear and Red switches, so I've tried them all (except MX green and grey, i guess), so I know something about which I speak.)
