Yii2-admin or dektrium/yii2-rbac?


I just want to confirm if those two extensions (yii2-admin & dektrium/yii2-rbac) can both be used in the same project, right now i’ve installed them without any conflict (along with dektrium/yii2-user), I found dektrium/yii2-rbac much more UI friendly & simple to use, but I wonder if yii2-admin has more functionalities to offer? I’m struggling to restrict access to r=admin other roles (I have 3 roles for this project: admin, user, partner. and I’m not using a specific permissions for now)
So my question: shall I remove yii2-admin extension? and use only use dektrium/yii2-rbac instead?
