The title is quite explicit : in a generic 'meta' game, which team has the best win rate, all other factors apart - blue one or purple (red) one ? Since it's not absolutely the same to play in the lower or upper part of the map, I'm quite sure there is a noticeable difference.
Does anyone have stats about it / way to check if possible ? What's your opinion about it or personal experience ?
Thanks again for the help.
