Solo: Ruins or Snowy.
Both maps has an incredible fast gameplay, and have the enough stuff to a equalled game. They also have good gold generators which are really essential to obsidian, tnt, apples among much other stuff.
Team: Pizza
To be honest, I don't play so much on Team Eggwars and I don't remember any other map that Pizza, this a good map which have a fast gameplay. I like the rush maps because I like to play fast in the majority of games, so I like these kind of maps, and this is one of them.
(Just remembered another map, Toys, besides the nostalgia what gives me, I also like his gameplay) {Edit}
