I think you'll find that the PT Essentials is VERY stripped down--more of an incentive to get you to buy the full version rather than a fully workable DAW. By all means try it but, unless you fall in love with the interface and decide the spend the money on "real" PT, you'll likely be better off with your existing Cubase (particularly if you already know the software).
Personally, despite using it for many years at work, I never came to actually like PT, only tolerate it. However, the choice of a UI and workflow pattern is a very personal thing so by all means experiment.
