I tried one of the recently purchased "modern model F"s. It felt a lot better than my old original model F battleship I sold for a lot of money about 7 years of. I don't know if it was how they felt in pristine condition, because the model F battleship was a lot older than me when I bought it.
The weighting is lower than the model M, and the action is smoother. It is however louder.
I like the Fs a lot more, but I type very lightly. Model M is almost too stiff for my pinkies. I thought about ordering a new model F. The repairability is amazing. The firmware as well.
But then I realized: I don't want a keyboard where I might have to open up and solder something back in. I just want one that works. Currently I rock a silenced MX brown, which I find OK, but the MX switches have lousy tactility. Topre keyboarss, or even a regular rubber dome keyboard, has a lot better tactility and almost no noise.
Had the Matias keyboards not had their quality problems I would definitely have used one of those. They are, IMO, the best modern switches feel-wise.
Other than that: I don't know why there aren't any topre-ish "opto-electric" keyboards out there. You would get the smoothness of opto-electric, the silent tactility of a rubber dome, with key register before bottoming out. MX brown is a lousy tactile switch, but the easily available competition (apart from topre) is even worse.
So: no. Unless you really love your model m and would like it smoother with the caveat that you might have to whip out a soldering iron in a year, I would not buy the new model F. The guy is doing a great job, and QC seems to be a high priority, but they haven't stood the test of time yet.
