Well, I like those episodes because each shows a good deal of character development for one particular character.
I can't really pin myself down to a single episode, as each has their own advantages. I will say that Jungle Cruise, as many have pointed out, is a fantastic episode; it has a visceral story and pulls some of the best music from the soundtrack (particularly at the end). But, Poker Face, Red Data, and Angels' Share are also excellent due to their individual character development.
I'm sure I'm forgetting a few episodes; the last few episodes of 2nd GIG were highly entertaining and action-packed; I'd have to rewatch the entire two seasons in a few days to remember and pin down one particular episode.
