[Aarohanam is same for all the 3 - sa ri ma pa ni Sa
Avarohanam - Madhyamaavathi - Sa ni pa ma ri sa
             Sree raagam - Sa ni pa ma ri ga ri sa
            Brindhaavanasaaranga - Sa ni pa ma ri (ga) sa

Madhyamaavathi and Sree are closer in mood. The essential difference lies in the manner in which the notes ri and ni are sung especially in avarohanam.
Note ri of sree raagam is always held without gamakam (followed by ga) while ri of Madhyamaavathi is generally held with kampitham often oscillating over a large range]

[In Brindhaavanasaaranga the movements are smooth, ri is not oscillated, ni is associated with Sa and there is occasional use of Kakali ni. The fleeting use of ga in 'ri ga' and a break after ga makes it quite different from the use of ga in Sree where it is explicit.Note ri is without kampitham and is strong]
