Hucaseal is overall better.
+less ata needed than any other hunter (and gets s.parts) so less to worry about end game gear wise.
+gets s.parts, d.parts, gratia, duel birds (granted I like Last Swan more but might as well use what you got). Point is has better unique equips than Huney. Just having s.parts, traps, and a ton more ata lets her fight a lot better really.
+traps, 3rd highest growing in freeze and confuse (every 10 levels)
+hits needed hp pools at 1 or 2 lower levels (951 hp at 140, 813 at 123, 721 at 112, 451 at 66 vs 950 at 143)
+Less of a pain to max out stat wise.
Granted Hunewearl does have some stuff:
+Hp needed for those levels isn't much worse and she has over 50/100 more defense at level 100/150 thus making her more able to take a hit overall better (and factoring in d/j supports)
+s/d, j/z level 20 freely for solo play and support along with resta and attack techs.
+only 30/50 less atp by 100/150 thus the amount she overall hits at isn't really that far off from Hucaseal. I mean come on 247 base damage vs 260 base damage isn't that extreme of a difference. Granted she has a very low ata growth rate so it can be a pain to use this.
