Zapdos

Though Zapdos competes with Rotom-W, it has several notable traits that separate it. Zapdos can threaten Ferrothorn while also checking Breloom and Scizor due to its access to Heat Wave. Its access to reliable recovery in Roost grants it much more longevity than Rotom-W, despite its vulnerability to Stealth Rock and sand. These traits allow it to see some use on sand teams as a Ground-immune Volt Switch user with good longevity. However, despite these promising traits, Rotom-W is generally used over Zapdos due to its Stealth Rock neutrality and resistance to Water- and Ice-type moves, allowing it to check Pokemon like Keldeo and Mamoswine. Zapdos also frequently gets forced out by strong special attackers like Latios, Alakazam, Reuniclus, Thundurus-T, and Volcarona. Outside of sand teams, Zapdos faces heavy competition with Thundurus-T, who is faster, stronger, and is immune to Electric courtesy of Volt Absorb.
