It depends. If it's a one-shot deal, I (personally) would prefer do() since it's more straightforward, and that's pretty much what it's for. If, however, you plan to do this in a loop, for many updates, so then you'd want to prepare() once, then execute() many times. But, in any case, you should still use placeholders in your do:

#Method 2 ( Use do() )
----------------------
$dbh = open_dbi();
my $sql = qq{ UPDATE
  $table{'logins'} SET online='N' WHERE nick=? });
  $dbh->do($sql, undef, $nick)
     or bail_out("Cannot execute UPDATE");
# Close connection
