Porcellio are a beginner friendly species because they can be left to their own devices for the most part. Minimal spraying is required, ONLY SPRAY THE MOSS, they still need water and a bit of humidity to breed and molt safely. Porcellio are protein driven, thus, you will need to place algae wafers/shrimp/dried mealworms etc. frequently. Territorial species are known to cannibalise and fight for food, so give those species more room, hides, and food.

Armadillidium are the for the more intermediate keepers. They aren't as drought-resistant as Porcellio, but they aren't as potentially aggressive or protein-motivated as them. They aren't particularly shy; they prefer being with more of their species and are relatively low maintenance. 

Ardentiella don't like moist substrate, so it is advised to spray the lid, moss, and sides of their enclosure. Laureola love moist soil, however, so spray everywhere to maintain the high humidity they want. All these species, outside of Ardentiella, are extremely shy especially with lower numbers, so don't worry if you don't really see them. All these species are more communal, so the more you have the happier they'll be and the more courageous they'll be. They are all pretty slow breeders, and the ones that require high humidity and temps are not suitable for beginners.
