well it does not matter for small sites! (you can increase the max connections if you like). And especially for people who don't know what they are doing with the main.cf (and theres a lot of them) should consider using the second configuration.

But of course if you know about the consequences and know how to avoid breaking the config you can use the first example... (I personally don't)
