Hello Balaji.....
Server Sundaram (directed by Krishnan-Panju but story, screenplay and dialogue by KB).
When all directors showed the 'Great Nagesh' as only a comedian, KB only trust on him and gave him challengeable rolls in his movies and brought out his multiple talents in several movies, such as
Neerkumizhi (hero)
Ethir Neechal (hero)
Iru Kodugal (somewhat villain)
Major Chandrakanth
Navagraham
Anubavi Raja Anubavi .....and so on.
You listed varieties of some of BR's village movies. If it is so, all KB movies are different varieties only. Cant compare one with another. You yourself ashamed to mention BR's some movies.

Once there was a quote: "Educated people will not see Tamil films, but only English and Hindi...like that". Only two giants made them to watch Tamil movies. One is 'Sreedhar' and the other is 'K.Balachander'.
