It's better than days old refrigerated food, but not equivalent to freshly picked.
I grow beans in my garden. French beans and broad beans are quite good frozen, perhaps amongst the vegetables that tolerate the freezer the most. Very happy to have those out of season. But there is no comparison possible with the fresh stuff.
Texture and flavor may suffer, but nutritionally, there is no real difference between fresh or frozen. And in the winter, frozen is sometimes the better choice as they are frozen at the peak of readiness.
