"Byomkesh" reel vs real life

It seems like the so called, much publicized rivalry between Bengali actors Jisshu Sengupta and Abir Chatterjee consists only in big screen not in real life. The actors who both portrayed the iconic "Byomkesh Bakshi" character on-screen respectively for their films "Byomkesh Bakshi" and "Har Har Byomkesh" have been in focus and pitted against each other on who played it best. But off-screen things seem to be completely different as the celebs refrain from back biting and praise each other's performances.
