Nitesh Tiwari and Vikas Bahl - Who is a better filmmaker?

Films directed by Nitesh Tiwari :

Dangal - Universally acclaimed film but starred Aamir Khan who is known for ghost directing all his films.

Chhichhore - Critically acclaimed and National award winning film.

Bhoothnath Returns - Above average film.

Films directed by Vikas Bahl :

Queen - Critically acclaimed and National award winning film. 

Super 30 - Critically acclaimed film.

Shaandaar - Only bad film directed by him.

Apart from this they both co-directed Chillar Party which also was a critically acclaimed and National award winning film.

Tiwari wins out 

Nitesh Tiwari any day, any time

Vikas's best is better but Nitesh is more consistent.

In my opinion,

Queen > Dangal > Chhichhore > Super 30 > Chillar Party > Bhoothnath Returns > Shaandaar
