Best for me

-Physical wind, only one I got a sub30 Nexus boss on (granted it's Earth Guardian) Dual awakening for Bartz, with awakening 1/2 and the earth one, sync/awakening/awakening 2 for Luneth and Vaan and chain on Luneth (wish I had Vaan's chain too)
-Magic Earth, Red XIII is still OP, and I got Maria's sync2 and dyad, those two are just so fast together, Emperor is slow though but he still contributes.
-Magic Wind, Fujin has a dual awakening and her awakening 1, Emperor sync and awakening, Eiko sync2 and awakening 1, Alphinaud is the weak link because his chain is slow because he doesn't have hero gear.
-Magic Dark Nabaat has imperils, is fast and has sync/awakening, Edea is fucking nuts with her dyad and dark sync and CoD is fantastic with her overstrike HA.

Worst for me

Bio (duh) I barely beat Wodin with 1 cap break on Thief, Edgar and Qustis, I keep putting tickets in FF1 in hopes of getting another one for Thief but no dice! Super worried about the nexus.
Magic Lightning- I think this is the most common non-bio one because of lack of imperils, still have to use Y'shtola solely because of that. Kraken and Blue Dragon are thankfully easy however.
Physical Ice- I have Trey with a dual awakening and sync and awakening for Josef, but Fran is really weak despite her sync and awakenings and she's my chain holder. I also have stuff for Celes and Squall but they're too slow to keep up with Enkidu.
