My experience has been anything but positive with GrabTaxi (it's called MyTeksi here in Malaysia). The biggest issues are:
* Since you need to specify your destination, taxi drivers can easily ignore you ("too far/near/congested").
* No rating system. This is Big Deal, as there's no incentive for the drivers to perform their best.
* More expensive than Uber (not sure in other countries, but it's true here).
* The app "feels" heavy, but this is subjective.
I initially welcomed them when they first launched, since it's difficult to hail taxi in Malaysia, but I was met with disappointment.
