Actually, Return of Samus is the best out of the 3 well-known ways to experience the darkest and most genocidal chapter in Samus' life. It's old, I get it, but it uses the Game Boy's limitations to create atmosphere and tension, and that's what this series is best known for. It deviated itself from the formula stablished by the first game, but somehow captures the same feelings of isolation, visceral horror and bittersweet adventure. The ending has to be one of the most impactful and groundbreaking moments in all of gaming, specially in how it tackled one of the hottest topics of debate this medium has sparked, violence in video games, as far back as 1991.
