Legendary Ike best IV

A unit like him doesnt really have a "best iv" since he could use any of them since hes so versatile. It depends more on what units you want him to check more and the playstyle.

They r both good decent ivs. Id keep the neutral one for future GHB if thats a concern for you

any boon is good for him but imho his best bane is -hp

Both are good ivs so it depends how you use him, as i concern the +def is slightly better than the neutral one but think carefully, probably the neutral one will fit more in your team.

Mine is a +10 merge +SPD/-HP. I personally think the plus speed really helps from being doubled.

I'd go with neutral, since his speed does help him out...but that's just me. I guess +def is better for QR, but if u use him when watching F2P GHB or BHB clears and stuff, you would need the neutral one more.
