Here's badlands, in general a map where a lot of approaches are viable from hardcore t1 all in to eco turtle and t3 rush, a lot of people like the map because it allows for big variety of play and doesn't punish early game mistakes as much, be it bo related or not.
From a quick count I see it has 28 safe mexes, 4 greyzone mexes and 4 highly contested mexes per player. It's a very heavy tip in favor of safe expansions. Now it doesn't mean they are always easy to get and will never be raided but you generally won't ever lose them outright but will only get delayed. This plus a moderate reclaim amount and the majority of games on badlands reach t2 and t3 stage which is more than a lot of 10x10 maps can offer, and it's by no means a turtle tech map.
Here's palms, another classic loved by most people
As you can see again overwhelming majority of mexes are clearly defined expansions that are closer to one of the players by a good margin. However due to how open the map is it is very easy to sneak units by and raid so none of the safe expansions are truly safe, this just generally leads to more aggression compared to badlands but overall I'd say the style of the game is shaped by how hectic the early game is and again it could become anything from t1 spamfest to an ecowar into t4.
Here's hollow, an extreme example of the opposite style.
I see 7 safe mexes, 4 greyzone mexes and 5.5 contested mexes per player. A staggering difference from the previous maps. Majority of games on hollow are hardcore t1 spam where a small BO whored efficiency advantage or a small mistake in raid defense are what often decides the game and the snowball is usually very hard to stop. This is just due to map control being absolutely crucial as a huge portion of map's eco is highly contested. From what I've seen from the games I played in the tourney maps generally lean towards this style. Personally I hate these kinds of maps but it definitely should not be abolished either, I'd rather see both styles and anything in between and further on the extremes, ideally weighted towards more tame solutions in general.
