I'm very lucky with the Xmas Banner

I spent 280(f2p) orbs on the new banner and it went very well;I found:
x2 W!Eirika, x2 W!Ephraim, x1 W!Fae, x1 Julia, x1 Loki, x1 Hector, x1 Sothe, x1 Ephraim and x1 Linde
I would like a tip,between -HP +Atk and +Res -Def W!Eirika,which should I use?Same with -Res +HP and -Res +Def W!Ephraim.
Anyway,my favourite Xmas unit is Ephraim
