I'm not sure about that whole "piano-like" debate.
Here's an analogy:
Piano = regular fuel car
MIDI controller = electric car
People want their electric car to feel familiar. Almost like they're driving a regular car. In this case yes, anybody's comparison will be dependent on their own taste, budget and driving experience.
In the case of the Fatar TP/100LR, it's more like somebody taped two motorcycles together and called it a car. It's got 4 wheels, sure. It can turn left and right, sure. But it just doesn't feel right.
It's not that it's not piano-like enough. It's that it feels off. Sure playing with the velocity curve can help but it's not gonna fix its inconsistent response. It doesn't give the physical feedback that most keyboard players need, to be able to play a passage exactly the way they hear it in their head (and nail it every single time).
At least, that's been my impression of this Fatar keybed so far, and that's been echoed by a lot of people. It seems to be good enough for a lot of people too though. But it's certainly not "the best-feeling hammer-action keybed around" as it's being advertised.
