Borderlands 2 leans clearly harder on execution.
Borderlands 2
Aim matters but generous hit feel
Pokémon Mystery Dungeon: Explorers of Sky

Borderlands 2 leans a little harder on reads, though the gap is small.
Borderlands 2
Enemies are scripted loot fodder
Pokémon Mystery Dungeon: Explorers of Sky
No adaptive opponent

Borderlands 2
Procedurally generated weapon drops vary
Pokémon Mystery Dungeon: Explorers of Sky
Random floors and item luck, cushioned by forgiving design
Borderlands 2 leans a little harder on optimization, though the gap is small.
Borderlands 2
Skill trees and gear math heavily solved
Pokémon Mystery Dungeon: Explorers of Sky
Type matchups, recruiting, and move sets are solvable
