Tactics and strategy in Heroes of Might and Magic V.

Whether or not to take Logistics depends on the map (IMHO). If the mines and passages to the enemy territory are guarded by hundreds of neutral creatures of level 4 or higher, the one who reaches them first won't be the one who moves faster, but the one who hits harder. In the vanilla campaign and both expansions, I only upgraded Logistics for Agrael. The others don't need to rush.

In general, whether or not to take any skill depends on the map. In all versions of Heroes. That's a fact. I completely agree.
However, there are certain values that are relevant in 80%, 90%, or 95% of cases. It is these patterns that, in my opinion, it makes sense to talk about. Without forgetting, of course, to add that this applies in most, but not all cases, and of course, it depends on the map.

However, there is a big difference between enemy territory and neutral territory.
In campaigns, the opponent is quite conditional. If you're not trying to set records, then it can probably be compared to playing tennis against a wall. I don't really believe that in most maps, there's nowhere to rush. And it seems that the one who runs around more, also levels up more (in a broad sense: both experience and visiting special buildings, and dwellings, and artifacts...).
