I navigated through the site and found that it is suggested to use Ruby

Ignore them. Use Perl.

There, now you have two opinions. Are you any the wiser?

• But yet I have a feel that Perl is more powerful

  Define "powerful"?

  (Hint:Anything you can do in Perl can be done in Ruby. And vice versa.)

• Need a clear understanding on which is better suitable for Enterprise kind of Application ??

  Define "Enterprise kind of Application"?

  (Hint: The term 'enterprise' in this context, is a label applied by the marketing men of expensive software to stroke the ego's of those they are trying to pursuade to pay their over-inflated prices.)

  Industrical strength software can be written in any general purpose programming language from assembler to Haskell. The defining factors include (but are not limited to), the expertise of the programmers; the thoroughness of the design; the rigour of the testing; the complexity of the application; the simplicity of the solution; the maintainability of the codebase.

  And the measure of all of these is a) subjective; b) much more reliant upon the procedures, practices and practitioners of the given implementation, than the language of implementation.

If you seriously want to arrive at a conclusion of which you personally prefer, (rather than just bear-baiting), then pick a moderately complex application and try to develop Perl and Ruby solutions to the same specification.

Depending upon the application; your own development and languages experience, (or that of your development team(s)); and the practices and procedures you (they), use; you will probably arrive at a conclusion quite early in the development.
