I wouldn't say it's "easier" because supposedly you cover the same amount of material. At the same time, it really depends on the professor that you take it with. I suggest taking it if you have the time to commit over the summer, want to lighten up your load during the school year. It's "easier" in the sense that you don't have to manage orgo with ~5 other classes (like you would during a regular semester), but at the same time, summer school means condensing one semester into less than a month, which means that everyday you cover a week's worth of material and you'll have an exam about once every 1.5 week.
