Dude, don't make me choose between Season Ten and Season Eleven. They're such good seasons, I can't decide which is better. So many of the best episodes of the show come from those seasons--"ChefBob," "SpongeBob's Place," "Karen's Virus," "Krabby Patty Creature Feature," "Feral Friends," and many, many more.

Yeah, I have a little hard time choosing but I always go with S10

I prefer 10 for its sheer percentage of goodness vs. badness, in fact, I'm about to start my mainly positive review. But season 9 as a whole was a masterpiece. I even found 9A incredibly enjoyable with great episodes like Bumper to Bumper, Squirrel Record, and of course Jailbreak!

Oml, season 1 and 10 season 3 ugh there so great im still a fan of season 1 what so ever.
