The choice between delta and Y is made mostly based on what wire you want (or have) to wind the motor. And it can be used to fine tune a wind to a desired Kv. Say for instance you want a motor with a Kv somewhere between a 3 turn Y and 4 turn Y, you could go with a 2 turn delta and the Kv would be equivalent to a 3.46 turn Y (2 x squareroot of 3). As for power handling, as long as you fill up the stator slots you'll have max power handling. Two motors wound to the same Kv and same total mass of copper used with one terminated Y and the other delta will both have the same power handling capability and will perform similarly (for all intents and purposes, a 7 turn Y will be the same motor as a 4 turn delta).
