Cruz,
Some more information for your reference ...
1.> MAS (S2500/S3500) also support PIM but not RIP
2.> MAS support IPv6 on management but no routing
3.> MAS certainly doesn't have EAPS (Extreme's propitary) but MAS has HLS (High Link Standby) which is for same reason to reduce L2 convergent time.
4.> For LAG/MLAG, what you put there is right. Maybe you want to add LACP for MAS.
5.> I'd suggest you to add security function which is what MAS has from Aruba controller and can easily beat other L2/L3 swithes.
