mild street, bridge, peripheral, what would be the best overall

 

depends on what you want the car to do. If you are looking for Max horse power and are willing to sacrifice street driveability and possibly engine life longevity, you will want a different port then if you want to retain street driveability.

 

well a huge street port would be the best for power and reliablitly, but even a brigde can be streetable, but prephreial ports are strickly racing

 

what would be the best overall

No, you have to choose your compromises. There is no best...
