Neither accounts are special. Thor is not praised for her paralyze, it's not a reliable affliction in the first place and as for Susanoo being strong, any SSR can be considered strong.

As mentioned already, aim for 2 or more SSRs, preferably will 2 of them being the same element or at least Sol with any other SSR kamihime.

Although you can just stick with one of the two you already have since who knows what you'll get from future gacha draws.
