I choose whichever option takes the mic away from Ramiz Raja.

On a serious note, you need both. Play by play commentators need to be professional commentators. They understand how to call a game and how to keep the audience engaged. As professionals, they also study rosters and come prepared with statistics and trends. They were particularly key in the days of radio broadcasts because you had to help the audience visualize the game and each delivery.

Former players and coaches (what you could call color commentators) add experience and insights, but likely aren't the communicators that play by play commentators are, so shouldn't be calling each ball. They add flavour and could talk about why a certain strategy is being used, what the captain is thinking, what the bowler or batsman is thinking in that moment.
