I understand it is called pusher configuration, can get better cruising speed. The US Army banned the pusher configuration in 1914 due to crashes.
I don't know about better cruising speed but definitely one of the factors which made NAL consider pusher config for Saras is lower engine noise inside the cabin.
at best, there may be only 2-4 pusher type of very limited production run aircraft flying in the whole world. Offhand I can think of one amreki and one eyetalian(?) company making them.
Since when has noise been a problem with Indian commuters?? If you sit anywhere behind
the engines in a boeing or airbus, noise is a major issue.
One major advantage is that the wings are aerodynamically clean and thereby more efficient.
It was extremely unwise to go for a pusher when it is not warranted. Certainly, many guys would have got their PhDs based on this aircraft claiming original "research".
