Mixpanel vs. Attribution Tools: Seeking Advice on ROAS and ROI

Hello! I am struggling a bit with attribution in Mixpanel and would like to know if Mixpanel has the ability to take the place of an attribution tool like ruleranalytics or attributionapp? Attribution works to a point but I find it difficult to work our ROAS or ROI. Anyone else going through this that would like to chat or anyone that could offer advise?
