My thought would be, as a coach, that a player should play against the best competition possible to improve for the HS season. Also, another coach may make something make sense to the player in question because he could word it differently or something of that nature that I couldn't get to click for the player. I suppose, however, that would require a coach who isn't arrogant, and it seems those coaches are in short supply. There are few good reasons for an able player to play HS summer ball over a "select" or travel team.
