I have both, as well as my personal favourite, Tread Upon Stars. Having them both is never a bad thing. If you need to choose one, I'd go with the Mida, since it's obviously a super strong weapon at this point in time. A lot of players use Hung Jury in the Crucible, but I've never been a fan. That, as well as Tread Upon Stars are more used in PvE for myself.
