Crawl space keeps plumbing - 2 different suggestions

[Jimmy Chao]

My crawl space has been filling with water and had 2 plumbers take a look.

1st plumber says that the gutter down sprout is broken. He recommends repairing and attaching the downsprout to a drain that leads away from house. This is because grading is really sloped into property which is why water is getting in. He says sump pump would not be necessary after this is done.

The 2nd plumber says to just install a sump pump.

Now, I do know the slope is graded into property, but digging trenches and install drains seem a little overboard. Would just a sump pump do? I am also thinking of grading the land to slope away from the property and extending downsprout.
