Does anybody uses ECU tuning tools used to unlock Hidden Features of a certain car? 
What can you recommend?

Depends on the make and model of vehicle and whats being done. If I am playing with ECU tunes on a ricer I can get away with SCT Advantage or something similar. But If I am getting into more detailed things like deleting DEF systems or say doing an ECU tune on something like a Hellcat that requires manufacturer specific tools with licensing and it gets very expensive. There are some tools out there that can do a little bit they can see diagnostic readouts and some other minor things but to do it correctly you need specific software from the manufacturer. Not all ECUs are created equal.
