Sorry to sound condescending, but questions like these make me wonder, what is wrong with engineers these days?
If you have to compare X framework to Y, all you need to do is understand the basics, and then compare the specs. If you are familiar with Hibernate, just go and read the specs of Entity. It isn't that hard.
Just think about the developers who used to work 30 years ago, with just a manual of the programming language itself.
I am not saying asking questions is bad but please understand, engineering is a specialization, and you are a specialist. You have to understand how everything works.
