I only use Manipulate and it allows me to illustrate all kinds of  advanced mathematics, including genuinely "bleeding edge" research (look at the Wolfram Demosntrations site and you will see some of it). I think it involves a lot of "significant ideas" and yet I have never come across any situation where I would want to use Dynamic (and DynamicModule). Furthermore, we have started teaching Mathematica here both in the context of general computer algebra and also for specific applications (including quite advanced applications in mathematical finance). We tell the students about Dynamic and show them a fee examples but then we only use Manipulate. If they want to know about Dynamic they are told to learn more by themselves. We have really top class students here, both in math and computer science but so far I have not yet met anyone who would find Manipulate insufficient - and they have created some quite spectacular projects with i

There probably aren't many limits to functionality you can have in
Manipulate but the layout is constrained whereas with DynamicModule
you can pretty much build whatever you want and make it look like
whatever you want. The best examples of this, that are accessible to
all, are the Wolfram CDF examples pack (I presume this is still
downloadable somewhere). These aren't Manipulates. And while on CDF
there is at least one thing that Manipulate can't currently do because
of a bug but DynamicModule can do (ClickPane) but there may be others.
