A softer golf ball is good for getting more feel off the clubface especially when it comes to hitting shots around the green, and when on it as well. In the past using a soft ball would've meant compromising on distance but this is not really the case anymore because of technology.
Balls with low-compression soft cores will feel softer off the face on full shots, with the added rebound properties of those soft cores also potentially helping those with low to average swing speeds hit it a little bit further compared to firmer-compression balls.
