There is barely any travel in the keys;
- The keys are closer together; and
- The key clicking sound isn't good.
All of this is a matter of taste. I find the feel of these keyboards really good. I honestly enjoy typing on them, I type a lot and I'm precise and fast. Some people, like yourself, dislike them. As I said - matter of taste.
Reliability, however, is not a matter of taste, and that's what OP was asking about.
I can only say that I had space bar double-typing issues with my 2016 MBP, and recently had the top replaced with a new 2017 keyboard. So far, it has been working great, but we'll see how it fares after a while. I do CPU intensive stuff and the computer does get quite warm, if anyone is wondering. I'm trying not to think about the keyboard failing and I use it like I normally would. I want at least a few more good years out of this laptop, as I really love working on it.
