The Fluffiest
Going back over season 6, I didn’t even dislike any of the episodes, there were just a couple really “meh” episodes like Flutter Brutter and 28 Pranks Later. Like, the worst one would probably be PPOV and that’s just bland, not awful. It was bookended by some great two parters, Gauntlet of Fire was awesome, and a good number of them were pretty good even if not great like Top Bolt, Gift of the Maud Pie and No Second Prances.

Oh 6 had a few real gems, but everything else was either meh or worse.
Fair enough. Just always puzzled me because I generally liked it, and it seems to get a fair amount of complaints.

I thought season 6 was an overall good season. A few hiccups here and there, but the rest was good.
I’ll agree with that.

I don’t really like using the term “best” in this context, as that implies an objective ranking to something I think is far too subjective. Personally, the first two seasons are still my favorites, with s5 very close to them; I also love s4, while s6 and s3 fall into the “like” category. (And as of right now, s7 ranks with the first two seasons; time will tell if it finishes as strongly as it has started.)

My favorite season is the one where they discover the forums and learn how to use them.
I feel like they need to do that one for season 8. I already have a mental image of Twilight standing in an actual Roman themed forum talking about how everyone there is so negative.  
Twilight: “I don’t understand why they aren’t listening. I think we need a new strategy Starlight. Starlight?”
[Starlight walks in covered in vegetable remnants.]
Starlight: “I think something’s wrong with these ponies. They pelted me with rotted vegetables just for showing up.”
Twilight: “What?! Did you tell them you’re my friend and protege?”
Starlight: “I tried, but there’s apparently a pretty large crowd here that thinks Luna and Celestia are the only real princesses in Equestria, and they brought the bushels of tomatoes to prove it.”

4 and 5 had some of the best episodes of the series. 7 is looking really solid too. 1 was fine for what it was. 2 and 3 were kind of uneven. 6 was a goddamn disaster.
I don’t get people’s problems with 6, but with the exception of 3 which I’ll agree was kind of uneven and a little lackluster, I’ve liked all the seasons. And so far, 7 is proving a really good one.

I prefer to judge individual episodes and story arcs. I don’t think it’s appropriate to judge an entire season in an episodic show like this. Maybe in a fully arc based show like game of thrones, but not here.
