Joy,
It really depends on what you're trying to achieve.
In older releases I used a class similar to CL_RECA_MESSAGE_LIST that I built myself, to collect messages for logging purposes. I wouldn't call that an "OO approach" per se, although it uses OO.
An important detail, however, that has nothing to do with OO: if you pass the message details (especially message class and number) to a method as literals, the where-used analysis on the message (from SE91) will not find this spot. So I found it useful to do more or less as follows:
DATA l_msgtext TYPE string.
MESSAGE ID if_consnts=>gc_m_cl TYPE 'E' NUMBER '25'
  WITH lv_msg
  INTO l_msgtext.
CALL FUNCTION 'BALW_BAPIRETURN_GET2'
  EXPORTING
    type   = sy-msgty
    cl     = sy-msgid
    number = sy-msgno
    par1   = sy-msgv1
  IMPORTING
    return = ls_return.
If you do it like this, the where-used analysis will find the spot. And if you replace the function BALW_BAPIRETURN_GET2 with something of your liking or you leave it as-is, that's up to you.
