300 blkout mix tape or jackl

I've been wanting to get a 300blkout pistol( I live in a tristate area and am constantly crossing state lines for work and to shoot and don't wanna deal with the sbr bs) for a while now, I loved PSA products for years and I can't decide the new mixtape or the jackl, I understand that they are two different guns, but still I would like to hear your opinions from owners of either or both, likes, dislikes, issues, whatever,
