DBD::SQLite: Insert or Update - Question

Question

While writing my question (howto: insert a new entry and if it exists already, update it) I found some answers in the Related Questions:

$sql = "INSERT OR REPLACE INTO $table ( Id, Name, Rating ) VALUES( ?, ?, ? )";
$sth_rating = $dbh->prepare( $sql );
$sth_rating->execute( $id, $name, $rating );

.

$sql = "INSERT OR IGNORE INTO $table ( Id, Name, Rating ) VALUES ( ?, ?, ? )";
$sth_rating = $dbh->prepare( $sql );
$sth_rating->execute( $id, $name, $rating );

$sql = "UPDATE $table SET Rating = ? WHERE Id = ?";
$sth_rating = $dbh->prepare( $sql );
$sth_rating->execute( $rating, $id );

Is the second method more safe then the first one?
