Season 7, let me tell you why. At least season 6 has quite a few sparkling gems, Suction Cup Symphony, Not Normal, Sand Castles in the Sand, Single Cell Anniversary, Chum Caverns and Krusty Krushers. Season 7 only has 3 episodes that really stand out, Karate Star, Enchanted Tiki Dreams and The Abrasive Side, the other good episodes seriously don't stand out. Not to mention it has a lot more terrible episodes than season 6, for example; A Pal for Gary, Stuck in the Wringer, Trenchbillies, Yours, Mine and Mine and a lot more. Also season 7 just recycled plots from older episodes like the Imitation Krabs knock-offs (3 included, yes 3 just from this season) Model Sponge was similar to As Seen on TV and I will admit Karate Star was very similar to Karate Choppers. For those 3 reasons I think season 7 fails in comparison to season 6.
