Okay, but like you're bouncing all over the place now. And not replying to my statements direct.

I understand that stored procedures can be more efficient, but again, EF has support for just calling stored procedures or views, so it's not EF's fault it devs don't use it.

If I "sort" in LINQ using LINQ to EF, it just adds an ORDER BY to the query it sends to the DB when you finally call .ToList(), so it is doing that on the database.

I don't understand what you mean by LINQ vs SQL... LINQ isn't an ORM, it's just a way for devs to write SQL using connectors like LINQ to SQL. The advtange of LINQ lies in it's ability to save .NET Developers time from wiring up a query and an object mapping when they need to do is db.Books.Where(book => book.Author == "George R.R. Martin");

Using EF doesn't prevent developers from doing any of powerful database things that you suggest doing. Maybe some developers don't know how to take advantage of these things, and that's what you've had to experience, but that's not EF's fault.

EF gives you the ability to decide where you leverage Stored Procedures and views, where you leverage ADO.NET and even where you can write your own SQL. The only thing EF does is track your entities in memory to know when they've changed. If you know when and where to leverage the database, EF will permit you to do so.

As Sam said you can switch from Lazy loading to Eager loading within EF in a few clicks with Lazy loading being the most used while Eager loading is good in some specific scenarios where you know that connected objects will be used in the future.

Also, use IQueryable vs IEnumerable to get the sorting done on the server.
However, it is evident that EF is slower than traditional SQL principles(connected and disconnected scenario) with the connected one being the fastest in pure speed. It's all about performance vs speed of development, and it really depends on the project you are working on.

I would go for EF with LINQ if performance is not a top priority, just because it saves so much time
