Advice on crank 53/39 vs 50/34?

So i am pretty new to biking so no nothing about this crankest ratios or anything, but I am playing on purchasing a road bike and I am definitely wanting to get a compact. So my question is what is the difference between these two (53/39 vs 50/34) I live in an area with mountains so I will have some long and some steep climbs. What crank will benefit me best. Any advice I would greatly appreciate. Thanks in advance!
