What was your favorite season based on content?

What season had the best content in your opinion? For me it had to be Season Six, I feel like it really tied the game together and heavily improved the quality for the end of its life cycle. I mean, we got awesome maps like Roundhouse, Makin, Courtyard, and Flak Tower, awesome guns like the Lewis Gun, Lee-Enfield, and grease gun, also that weird SMG with the half-moon mag, does anyone remember that one? Anyway, that’s my favorite season and I want to know what your guys is.
