But in all seriousness, I really do think that my favorite AT episodes are the ones that make the cogs in my brain turn ultra fast.  (And the ones that hit me in the feels, I suppose, though these two things are not necessarily mutually exclusive.)  The reason I ended up really liking the season five opening two-parter in the first place was for the indirect character development and worldbuilding, after all.

not that I don't like the less worldbuilding- or charter-focused episodes or anything like thatfor example Time Sandwich was greatI just really like worldbuilding and character developmentI ge the same way about character arcs and character development as some people get about shippingwell okay maybe not that extremeat least not on the surfacebut I just really like worldbuilding and character development okayI really need to write up some of my narrative theory stuff someday
