I'd go with a planet that has frequent storms that stops electrical, or at least the advanced stuff, equipment from working.
No drones, no satellite...etc
Then for the actual Ground. I would go with a series of very large island were the sea is near impossible to cross without proper equipment, that separates the groups but also if someone is determined enough they can cross it
Then for the Islands I think the ideal conditions would be if they are far enough from each other so that they have very different geography not limited to the ones below.
So I'll just assume that the islands, again large things not small dots of land, have very different features.
A large mountain range with a complex system of caves, mines, underground lakes...etc. Would provide quite a challenge for any hunter.
Not only can't they see their prey or track it, but it's huge enough to consume time. Also the nature of the close quarters would mean that modern/space weapons take somewhat of a hit. An attacker could always have the element of surprise.
Not to mention rigging places to collapse, making traps...etc.
Absurdly thick and lush forests complete with large beasts and poisonous creatures.
Another hellish environment where the hunter has to keep their guard all the time and have to focus and use more traditional methods rather than relay on tech.
The hunted should be at least familiar with the type of forest because with minimum equipment they would just die.
So a veteran soldier or someone from a similar world against your hunters is ideal.
Again not a lot of visibility. traps, treacherous terrain, and predators both in the form of large killer creatures and small but still dangerous ones.
Urban ruins. Obviously this requires either having ruins on the planet or making them for the hunt. But either way urban settings are quite fun.
Close quarter fighting, thick large materials for cover, a network of buildings and passages, snipers, and large amounts of materials for traps and weapons.
I think those are the most fun and diverse settings suitable for a hunt.
There are a lot of other places or scenarios but that's what I would go with.
