I've been learning both TC and DC.
If you're thinking of using TC pro, keep in mind that its retail price is about 14 times higher than that of DC.
But for what you're doing its likely that TC Deluxe will work as well. TCD is about twice the price of DC.
The two products (DC & TCD) are about equally the same difficulty to learn, with some advantage to TC because movement through space is a little more intuitive (you have to have things set up right in DC for movement to be intuitive). Also, the TC control panel (might be using the wrong term) gives you quick access to an object's size , scale changes, exact position. I was surprised to find that you couldn't just change the Z position of an object, for instance, natively in DC (though you can write a macro to do this). DC has an older feel, with most every action mediated by a dialog rather than the control bar as in TC. You need to use the information box all the time in DC, but on my system this box slides open and closed lazily rather than opening crisply.
If you want a photo-realistic rendering, then TC/TCD is the best way to go. You can get some nice renderings in DC, but not quite photo-realistic. The rendering options in DC seem to have been tacked on, and some features (like rendering a section, or rendering modes that don't show text) don't seem to work. There's about 7 different ways of rendering (hidden line, hidden line with acceleration, Quick, Quick with acceleration, Gouraud, Gouraud with acceleration, and Phong no acceleration) and the results can be completely different for each choice.
If you want to produce professional looking output, then you will need paperspace features. If you get DC, be sure its v21 as there were some flaws in prior editions. Both TCD and DC v21 have paperspace, but TCD's is more robust.
Compared to TCD, DC has macros, 3D filleting, and something similar to lofting. DC can take planes and grids and cement them together into a solid which you can't with TCD. DC has a native way of moving and position objects that's pretty cool. So its feature list -- especially with 3D objects -- is a little longer than TCD's. However, 3D manipulations in DC sometimes result in broken objects. The macro language is like something from 1971. DC has the ability to produce a cross-section from 3D objects -- something that is only available in the pro version of TC. You can probably replicate this feature in TCD by actually slicing a copy of an object.
Apparently DC can not put a true hole in a plane, and by an extension in 3D objects. Whenever you put a hole into a plane, an invisible "fracture" line is also present. Usually it is invisible, but sometimes it becomes visible and you need to hide it. Apparently this puts some sort of upper limit on the number of holes you can reasonably put in a board, though that number is generally higher than what most people will need. Unless they're doing a speaker grid. If a limitation like this exists in TCD I haven't noticed.
Note that neither TCD nor DC use true solids -- both use "hollow" objects.
If money is no object, then obviously TC pro is the winner -- but you could buy a lot of shop equipment for the price. (Somebody will now come along and suggest that you can buy an older version of TC Pro at a reduced price. But comparing arbitrary street prices against stated retail prices is highly subjective).
Probably for basic wood work, TCD is a good choice with a generally more sophisticated experience.
But DC is cheaper and should do it too, after you figure out any work-arounds. DC may offer more options than TCD if you decide to branch out into metal work as well.
Ok, that may have been more confusing than helpful, but give you some things to consider. If on any of these points you have questions, be sure to ask in the appropriate forum. I may have gotten my facts mixed up. Both DC and TC have good supporting forum members.
