So it's been about 3 weeks since I've been typing with a Realforce 55g (in a 103UB) at the office and Cherry Browns (in a Filco tenkeyless) at home and I thought I'd share some medium term observations to compliment the short term observations I made in my "it's in the mail" thread
here.
I love the feel of the PBT keycaps. This is the UB version and although I would like to be able to read the key legends better than this (it looks blank to me most of the time even at the office) it hasn't caused me too many problems. The Filco caps are wearing OK, but don't feel nearly as nice as the Realforce caps. OTOH, between the original 103UB owner and myself the spacebar is already developing a little shiny spot. The Filco is still completely shine free.
In terms of noise there is no comparison - the RF is miles quieter than the Cherry, even when I'm typing really light and slow trying to make the Cherry as quiet as possible. If you need quiet - Realforce wins over Cherry. Most of the noise from the Cherry is from the caps, so this won't change depending on which switch you chose. It may vary depending on the board and whether it is PCB or plate mounted, what the caps are like, case resonance etc... I also type on a model M, and both boards are "silent" compared to that.
In terms of switch feel, the Topre 55g is FAR FAR FAR more tactile than the Cherry brown. There's a nice popping yield when pressing the Topre switch. Also, the Topre switch seems to have no drag resistance of any sort - as if the mechanism floats with no contact or everything internally is made from high grade teflon. My MXs have over 4 weeks on them and they still feel gritty and like something is dragging inside. This is probably the little "tactile bump" mechanism and blacks or reds wouldn't have this gritty feel.
The Topres have the best off-axis binding characteristics of any switch I've ever used. Right out of the box I ooohed and aaaahed over the unique feel compared to anything else I've typed on. The thocky sound and feel is also great. I really like the force curve feeling compared to the Cherry which is always linearly increasing even on a "tactile" switch. The Topre space bar whacks a little, and the larger keys (shift, enter, BS) have a bit of a metallic rattle to them on down and up stroke.
At speed the Cherrys don't feel tactile at all. At speed I can easily tell the difference between blacks and browns, that's not what I'm saying, but my mind/muscle does not perceive "tactile bumps" as the difference that I feel. I don't know how else to describe it. I still haven't had a chance to try Cherry clears.
An interesting observation, however, is that despite liking the individual feeling of the Topre 55g better than the Cherry, I am not faster or, overall, more comfortable on the Topre. When typing quickly on the Cherry (i.e. natural english prose in email or IM as opposed to code) I find that I roll from key to key and ramp up to a faster speed. On the Topre my mind/muscle seems to be pressing one key at a time and focusing on the press/release before moving on. Typing on a cherry is like "abcd.efg.h.ijklmn.o.pqrstuvwxyz". Typing on the Topre 55g is like "A B C..D.EF.G.H.I.JK.L.M.N". You get the idea.
I'm thinking that the 55g is too heavy for me to get fast and fluid on which is why I'm watching for a variable force. I'm also a little worried about all the comments I hear that the 30/35g keys aren't tactile at all. The tactility feels so great on the 55g, I'd hate for half of a variable board to feel linear. On the other hand, perhaps 55g is "over tactile" which is what's causing what I'm observing.
I find it odd that I don't exhibit the same typing pattern on model Ms or 10 year old Keytronics boards which are uniform 55g weighting (just like my Topre) before going to ergo variable (kind of like variable Topre). I'm smooth and fluid on a Keytronic and Model M as well with out the stuttering I see on the Realforce. Anyone else observed this?
So I'm looking for a Realforce 86U/87U with variable keys and preferably legends I can read so that I can determine if variable Topres are right for me. I haven't decided whether to keep the 55g while I think about it and enjoy it until then or whether to sell immediately. After looking at
this thread, what I really want is a gold/black/black 87U US ANSI variable force
