I'd like some advice regarding the summer 2019 eidolon/summon miracle tickets.

I lack any of the 100% or 140% summons, and I have Gaia and Sol that can go into almost any team. Would Diaboros (magic release) be the most value for me? The others have really strong stats and skills, but unless I'm misunderstanding Diaboros main skill she just seems incredibly strong as a main summon, and would afford me to play around with all elements more easily just with her as main summon.
