Tips: ESC Controller vs. BLDC Motor Driver

They are usually the same. The main difference between the different solutions is how they commutate and what interfaces they use. Usually, they use a fairly poor trapezoidal commutation with zero cross detection. Some of the better ESC or BLDC controllers use trapezoidal commutation with flux integration, which usually works better. Others can also use flux-integrated sensing or encoders for some FOC-like commutation. This is usually suitable for low-speed torque but requires more processing so higher speeds may be problematic and therefore is not usually used for multi-rotor drones. The cheaper ones will have servo PWM inputs, and some of the more advanced ones may use something like a CAN bus, but that's not very common yet.
