I don't think it's either in particular, I think it's good planning. Guardiola likes the players to get plenty of rest, something that came up a couple of times in the commentary, and come the end of the season we're able to do what we need to do.
Liverpool, on the other hand, had an intensive training camp, played an intensive game today and made it clear how they're going to approach the season. Pretty much the same as they did last season, and look how that ended for them. They were clearly knackered at the end of it. Who's prep would you rather have?
