For me it's about how they convey the current flow of the game that matters. The way I follow baseball is listening to it while doing other things. I want them to convey the (for lack of a better term) urgency of any given moment. If they're laid back and joking I know that moment is in a bit of a lull so there is no need to pay strict attention. During those times I really don't need to hear about the count, number of outs or the score. If there is intensity in their voice I know something worth hearing is going on. That's really the only time I care about the mechanics of the game like score, number of outs, balls and strikes and such. In those moments where nothing is really going on I do enjoy them giving me background information about players and the team and such as well.
