What are the differences between these 2 queries:

SELECT * 
FROM Titre
WHERE DateInsertion = (
	SELECT MAX(DateInsertion)
	FROM Titre)

AND

SELECT * 
FROM Titre
WHERE DateInsertion = (
	SELECT TOP 1 DateInsertion
	FROM Titre
	ORDER BY DateInsertion DESC)

I found that the second syntax can be a lot faster.

Can I safely replace my SELECT MAX with SELECT TOP?
