It depends a bit what specific stacks you are interested in.  Pluralsight and Lynda&#x27;s &quot;all you can eat&quot; monthly subscriptions are probably the best since they just have more classes all around.  Lynda by and far has the most classes available.  They have more tech classes than Pluralsight, but they also have classes in many unrelated categories as well.  The flip side; I think Pluralsight holds content authors to a higher standard.  Once Pluralsight was heavily focuses on .NET, but they&#x27;ve branched out a lot more.<p>Coursera has some good stuff and it&#x27;s free if you don&#x27;t care about the cert.  Their Functional Programming in Scala class is excellent.
