User blog comment:Mohamed7845/Dion/Kira Who is Better/@comment-26957321-20150915102106

I just have one thing to say having both of them (urgh I want a 7* spark buffer) Kira well carrying only 4 buffs 1 being sup par (atk/def down) the other 2 being common (200% atk buff & def ignore), is less "meta" then Dion as Dion provide crit, BB atk and Spark. But Dion splits his 3 buffs into BB and SBB respectively, in terms of UBB there are tons of UBB way better than his so let's just compare BB and SBB.

For Kira, his BB and SBB both provides 60% crit rate, BB is ignore def and SBB is atk/def down.

For Dion, his BB gives 60% crit rate and SBB gives 200% BB atk.

So if we compare based on buffs Dion wins, but in terms of usability and auto-battle friendliness Kira is better.

Let's not forget that Kira attacks in Light & Dark, giving him pripority to strike before add elements (in the case of light and dark enemies only) while Dion only attacks in Earth so often require activation AFTER an element buffer.

Another key winning factor of Kira is his Sparkability. Most people run Double Kira's with Zenia/Raaga for Dion it would be Rhoa/Zedus/Loch (not sure if there are any Earth/Thunder Spark units). I would say that Kira sparks more times than Dion because Dion's animation is too fast, all the damage/hits are clustered.

Lastly you need 2 turns to benefit from Dion's full buff for Kira, 1 turn is sufficient. Unless you run double Dions, but then again a double Kira can also have crit rate, ignore def and atk/def down.

TL;DR: Kira is slightly better.
