My top 3 of the second half:
The Last Roundup - Even if you take away the Derpy scene, this is still a great episode (and one to show if you want to introduce anyone to Friendship is Magic). While you can predict the reason for Applejack not wanting to return to Ponyville early on (and a very understandable reason at that), the journey is still a fun one with plenty of laughs, a thrilling chase scene, and very sweet heartwarming moment at the end.
Putting Your Hoof Down - Yes, it's true that it has some "jerk" issues early on, but once Iron Will enters the picture, things begin to pick up. Among the pluses include an enjoyable antagonist in Iron Will (both in his personality and the fact that he's not really a jerk when compared to other one-shot antagonists), "assertive" Fluttershy feeling more natural than the version of "Fluttercruel" seen in Return of Harmony, and some great chemistry between her, Rarity, and Pinkie Pie (as having fellow Mane Six ponies in a strong supporting role was missing from the three episodes preceding this one). Besides, you can't help but give Fluttershy a comforting hug after the "I'm the monster" scene (especially with her doing the "reverse squee").
Hurricane Fluttershy - Another Fluttershy episode, but definitely deserving of the top three spot. Like The Last Roundup, there's a great mixture of "fanservice" (Fluttershy as a tree), humor (the muscular pony constantly going "YEAH!") and heart (the story's plot about Fluttershy being concerned about embarrassing herself when it comes to taking part in the tornado to deliver water to Cloudsdale for the rain season. Another plus is that after so many episodes this season where Rainbow Dash comes off as somewhat of a jerk, we finally see her in a more positive light here as she shows concern about Fluttershy being afraid of embarrassment and is determined to still bring water to Cloudsdale when a number of Pegasi getting sick results in the possibility of the whirlwind created by Ponyville's Pegasi not having enough power to complete the task at hand.
