X2. The movies and then new seasons were okay, but in a different way where they kind of seemed to be caricatures of the original run.
Jurassic Bark is always the mentioned best episode with Futurama, but it (and Luck of the Fryish) is just so sad. Not that they aren't good episodes, but the Luna Park episode in season 1 (with Bender assaulting the mascot, the "moonbillies"), then Bender getting hooked on electricity in Hell is Other Robots and even Mars University with Gunter's classic line (https://m.youtube.com/watch?v=uqjv0mHpapk) are all great. Godfellas and Pharoah to Remember are also underrated.
