I am very much confused to select best sfm faculty?

Aditya Jain sir has a very deep knowledge about the subject and his practical approach towards the subject helps understand the concepts very easily.

and about 95% of his students are said to be scoring full marks or very great marks

You dont need to be confused anymore, CA Aaditya Jain is great for CA Final SFM and his notes and concepts are just mindblowing.

You should join the classes of him if you wants to score great marks in SFM.

There are various great teachers for SFM. You could check out CCI Online Learning for various faculty recommendations and choose one according to your convenience. I will link the CCI Online Learning website for you:-
