Weird phrasing?

[Ulysses]

In this sentence:

Routine doctor checkups allow diseases to be detected early.

Or is this better:

Routine doctor checkups detect diseases early.

Which one is grammatically correct?

[rws_killer5]

Both are grammatically correct; however, I would prefer the first one because it is used more often by Americans.

Just curious, are you an American? Or did you just randomly down your location?

[Ulysses]

Nope, I'm really just unsure of whether detection should be grammatically more direct or not.

[rws_killer5]

what do you mean by more grammatically direct or not?
