just want to know which core file pattern is best to set for core dumps:

I will really appreciate an explanation why the chosen one is better.

NAME
gcore - Generate a core file of a running program
SYNOPSIS
gcore [-o filename] pid
DESCRIPTION
Generate a core dump of a running program with process ID pid. Produced file is equivalent to a kernel produced core file as if the
process crashed (and if "ulimit -c" were used to set up an appropriate core dump limit). Unlike after a crash, after gcore the program
remains running without any change.
OPTIONS
-o filename
The optional argument filename specifies the file name where to put the core dump. If not specified, the file name defaults to
core.pid, where pid is the running program process ID.

properly installed at your site, the command
info gdb
should give you access to the complete manual.
